Product Introduction

The structure is shown in the figure below:

1.1. Operating Conditions

1.1.1. The operating environment must comply with Sections 3.1.4 and 3.2 of GB/T10058-2009.

1.1.2. Guide Rail Processing Method: /B. Guide rails processed by planing, cutting, or grinding must comply with the following standards: GB/T22562-2008 and JG/T5072.1-1996.

1.1.3. If the safety clamp is operated with oil, a certified oil must be used. Failure to do so may cause the safety clamp to fail.

1.1.4. If the safety clamp is operated without oil, oil must not be applied to the guide rail surface. Failure to do so may cause the safety clamp to fail.

2. Installation Requirements

2.1. Pre-Installation Inspection

2.1.1. The safety clamp parameters must be consistent with the actual elevator parameters.

2.1.2. The safety clamp seal must be intact.

2.1.3. The safety clamp is intact.

2.2. Installation Technical Requirements

The safety clamp's appearance and installation dimensions are shown in the figure below:

2.2.1. After assembly, clamping and resetting should be smooth.

2.2.2. The engagement distance between the brake wheel and the guide rail is 21 ± 2 mm (the distance from the top of the guide rail to the safety clamp mounting surface is 24 mm).

2.2.3. The clearance between the brake wheel and the guide rail is 3 ± 0.5 mm.

2.2.4. Adjust the linkage mechanism so that the two rollers of the two safety clamps contact the guide rail synchronously.

2.2.5. After installation, effectively remove any impurities such as rust preventative oil, welding slag, concrete, and sand from the guide rail surface and wipe the rail dry. Inspection method: Wipe the guide rail with a white cloth; there should be no visible oil stains on the cloth.

2.3. The safety clamp can be installed in either a fixed or floating manner.

2.3.1 When using a fixed installation method, where the safety gear and the straight beam are directly bolted together through the screw holes on the back of the safety gear, elastic guide shoes should be used. The elastic compression of the guide shoes should be at least 4mm.

2.3.2 Installation of Floating Components (Using one installation method as an example, as shown in the figure)

2.3.2.1. Before installation, apply lithium-based grease to the floating bracket and the back of the safety clamp.

2.3.2.2. The floating spring should be on the same side as the brake wheel.

2.3.2.3. Adjust the stop bolts so that the distance between the safety clamp brake wheel and the guide rail meets the requirements of 2.2.3.

2.3.2.4. The distance between the floating bracket and the stop column is 6 mm.

2.3.2.5. After installation, push the safety clamp to compress the floating spring. The safety clamp will move flexibly left and right. After the external force is removed, the safety clamp will return to its initial position.

2.3.2.6. The force in the normal operating position after the floating spring is compressed should be greater than 100 N.

2.3.2.7. After installation, check the above-mentioned dimensions and record the following key dimensions.

2.4. Electrical Installation

2.4.1. The system schematic diagram is shown below (for reference only).

Electromagnetic chucks 1 and 2 require a DC12V voltage and must be wired in series. Electromagnets 1 and 2 require a DC110V voltage and must be wired in parallel. Safety clamp actuation detection switches S1 and S2 must be connected in series to the safety circuit.

If our junction box is not selected, it is recommended to refer to the design. It is recommended to configure a power-off hold function (which temporarily holds the chuck in place during a power outage, preferably for at least 2 seconds) and a power-off self-reset function for fault-free operation (the energized electromagnet resets upon power-up and then automatically de-energizes). A self-test function is also provided for the electromagnet.

2.4.2 Controller Wiring

2.4.2.1 The controller wiring diagram is as follows:

2.4.2.2 Functional Description

After the controller is powered on, the battery charges (automatically, requiring no intervention). During charging, the charging indicator flashes. After charging is complete, the charging indicator remains on. (The controller can still be used normally during charging, but the charging time is longer, so do not worry about it.)

Under normal conditions, after power is applied, the controller waits for 2 seconds, the electromagnet engages for 0.3 seconds, and then remains engaged. The safety clamp is released, the power indicator remains on, and the fault output indicator also remains on (constantly on indicates no fault, the fault output relay is engaged, and the contacts are also closed).

Under normal operating conditions (normally closed signal input to the overspeed switch), if the overspeed switch is released, the electromagnetic chuck will disconnect, the safety clamp will lock, the power indicator will flash (indicating a fault), and the fault output indicator will go off (the fault output relay is disconnected). This fault condition requires the reset button to recover; it cannot be recovered by a power outage.
