Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rail processing, in particular to a clamp for fixing an elevator guide rail. Background Art

[0002] The elevator guide rail is an elevator component composed of a steel rail and a connecting plate. It is divided into a car guide rail and a counterweight guide rail. From the cross-sectional shape, it can be divided into three forms: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rail bears the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc. The magnitude of these forces is related to the load and speed of the elevator. Therefore, the guide rail should be selected according to the elevator speed and load. Most of the elevator guide rails are connected and fixed by yin and yang tenons. When processing the elevator guide rails, corresponding fixtures are required for fixing. After searching, the Chinese patent publication number CN214108951U discloses an elevator guide rail yin and yang tenon milling machine, including a base and a hydraulic fixture. The setting of the travel handwheel and the guide roller in the hydraulic fixture can drive the guide roller to rotate by turning the travel handwheel, thereby driving the elevator guide rail above the guide roller to smoothly extend into the bottom of the locking push rod in the hydraulic fixture, which is convenient for adjusting the extension length of the elevator guide rail, which is extremely convenient.

The operation of the two first electric push rods 42 can drive the clamping plates 43 on both sides to move relative to each other, so that the T-shaped elevator guide rail 2 can be clamped, and the two sides move synchronously, which can ensure that the T-shaped elevator guide rail 2 is coaxial with the yin-yang tenon, so that the processing accuracy can be improved, thereby solving the problem that the existing device only clamps the top of the elevator guide rail, but cannot clamp the two sides of the elevator guide rail, which is prone to deviation.

[0022] A second receiving groove 44 is provided on one side of the outer surface of the clamping plate 43, and a spring 45 is fixedly connected to the inner wall of the second receiving groove 44, and the other end of the spring 45 is fixedly connected to a connecting plate 46 which is slidably connected to the inner wall of the second receiving groove 44, and a plurality of first brackets 47 are fixedly connected to one side of the outer surface of the connecting plate 46, and a guide wheel 48 is rotatably connected inside the first bracket 47. When the clamping plates 43 on both sides are loosened, the guide wheel 48 can pre-clamp and guide the T-shaped elevator guide rail 2 under the action of the spring 45, thereby avoiding wear of the clamping plate 43 when the T-shaped elevator guide rail 2 moves, thereby improving the service life.

[0023] Embodiment 2:

[0024] like Figure 1 and Figure 3As shown, a long groove 5 is provided on the lower surface of the base 1, and a lifting and moving mechanism 6 for moving the T-shaped elevator guide rail 2 is installed inside the long groove 5. The lifting and moving mechanism 6 includes a first motor 61 embedded and fixedly installed on the top of the long groove 5, and the output shaft of the first motor 61 is fixedly connected with a screw rod 62. The outer surface of the screw rod 62 is threadedly connected to a lifting plate 63 that is slidably connected to the inner wall of the long groove 5. The upper surface of the lifting plate 63 is symmetrically fixedly connected with two second brackets 64, and the interior of the second bracket 64 is rotatably connected to a driving wheel 65, and the outer surface of the second bracket 64 is fixedly installed with a second motor 66 connected to the driving wheel 65. Two through holes are symmetrically provided on the upper surface of the base 1 and located between the two side panels 3. The second bracket 64 is located inside the corresponding through holes. When the length of the T-shaped elevator guide rail 2 needs to be adjusted, the first motor 61 is started at this time, and the first motor 61 rotates the lead screw 62 to rotate, and the lifting plate 63 and the driving wheel 65 are driven to move upward through the thread, thereby lifting the T-shaped elevator guide rail 2, and then the second motor 66 is started to drive the driving wheel 65 to rotate, so that the T-shaped elevator guide rail 2 can be automatically driven to move, and no wear is caused to the upper surface of the base 1, thereby solving the problem that the existing device needs to manually drive the elevator guide rail to move, which increases the workload and easily causes wear to the clamp.

When in use, the second electric push rod 72 operates to move the pressing plate 75 to the top of the T-shaped elevator guide rail 2, and then the third electric push rod 74 is started to drive the pressing plate 75 to move downward, so that the T-shaped elevator guide rail 2 can be clamped to avoid jumping, and when the T-shaped elevator guide rail 2 is removed, the second electric push rod 72 can operate to retract the pressing plate 75, so that the T-shaped elevator guide rail 2 can be lifted and removed by the bracket, thereby improving work efficiency, thereby solving the problem that the locking support position of the existing device is fixed, and the elevator guide rail can only be pulled out to achieve installation and removal, which increases the workload and reduces the work efficiency.

[0027] Working principle: When in use, first install the clamp at the corresponding position through the mounting hole 8, then place the T-shaped elevator guide rail 2 between the two side plates 3, and then start the first electric push rods 42 on both sides. The operation of the two first electric push rods 42 can drive the clamping plates 43 on both sides to move relative to each other, so that the T-shaped elevator guide rail 2 can be clamped, and the two sides move synchronously, which can ensure that the T-shaped elevator guide rail 2 is coaxial with the yin-yang tenon, thereby improving the processing accuracy, thereby solving the problem that the existing device only clamps the top of the elevator guide rail, cannot clamp the two sides of the elevator guide rail, and is prone to deviation, and then start The second electric push rod 72 is driven to operate so that the pressure plate 75 moves to the top of the T-shaped elevator guide rail 2, and then the third electric push rod 74 is started to drive the pressure plate 75 to move downward, so that the T-shaped elevator guide rail 2 can be compressed to avoid jumping, and when the T-shaped elevator guide rail 2 is removed, the second electric push rod 72 can operate to retract the pressure plate 75, so that the T-shaped elevator guide rail 2 can be lifted and removed by the bracket, thereby improving work efficiency, thereby solving the problem that the locking support position of the existing device is fixed, and the elevator guide rail can only be pulled out to achieve installation and removal, which increases the workload and reduces work efficiency.
