Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance technology, specifically to a rapid inspection device for elevator brake clearance. Background Technology

[0002] Elevator brakes are an indispensable safety device in elevators, also known as holding brakes. They play a braking role when the elevator stops or in an emergency, ensuring the safe operation of the elevator. The working principle of the brake is mainly that when the power is on, electromagnetic force is generated, which separates the friction plate from the brake wheel, allowing the traction sheave to rotate and the elevator to operate normally; when the power is lost, the electromagnetic force disappears, and the friction plate contacts the brake wheel under the action of the brake spring, generating friction force to stop the elevator.

[0003] A proper brake clearance ensures the normal operation and safety of the elevator. If the clearance is too small, the brake may fail to open or close properly, affecting the elevator's operation. If the clearance is too large, insufficient braking force may occur, affecting the elevator's braking effect. In existing technologies, feeler gauges are typically used to measure the brake clearance. However, adjusting the feeler gauge to measure the thickness requires repeatedly pulling it out of the clearance, rotating and unfolding an additional feeler gauge, and inserting it into the brake clearance from thin to thick, which is inconvenient. Therefore, a rapid elevator brake clearance inspection device is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: When adjusting the feeler gauge to measure the thickness, it is necessary to pull the feeler gauge out of the gap multiple times, rotate and unfold an additional feeler gauge, and insert the feeler gauge into the gap of the brake from thin to thick, which is inconvenient to operate.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A rapid inspection device for elevator brake clearance includes a guide mechanism, wherein a measuring mechanism is provided inside the guide mechanism;

[0007] The guiding mechanism includes a housing, one side of which has a mounting groove, and several threaded holes are provided at the edge of the mounting groove surface. A cover plate is also movably mounted on the inner side of the mounting groove.

[0008] Among them, screws are connected through the cover plate near each threaded hole, and each screw on the cover plate surface is connected to the thread inside the threaded hole;

[0009] The cover plate has grooves on the middle and upper and lower sides of its surface. Each groove extends horizontally and a slider is slidably connected inside each groove. A shaft is fixedly connected to the side of the slider closest to the inside of the outer shell, and a push plate is fixedly connected to the side of the slider away from the shaft.

[0010] As a further embodiment of this utility model: magnetic blocks are fixedly connected to both sides of the inner wall of each of the slide grooves, and the outer wall of the magnetic blocks is also magnetically connected to the slider.

[0011] As a further embodiment of this utility model: a lubrication port is provided on the top side of one side of the outer shell, a dust plug is engaged inside the lubrication port, a strap is fixed to the top side of the dust plug, and the dust plug is fixedly connected to the outer shell at the other end of the strap.

[0012] As a further embodiment of this utility model: a handle is fixedly connected to the outer shell on the side away from the dust plug.

[0013] As a further embodiment of this utility model: the measuring mechanism includes a feeler gauge one, a feeler gauge two is slidably connected to one side of the feeler gauge one, and a feeler gauge three is slidably connected to the feeler gauge two on the side away from the feeler gauge one.

[0016] The beneficial effects of this utility model are:

[0017] This invention uses a slider on the surface of the outer shell to extend and retract the feeler gauge. Multiple sliders are provided to extend and retract different feeler gauges, which facilitates quick detection of brake gaps without the need to frequently pull the feeler gauges out and adjust them within the gap, thus improving gap detection efficiency.

[0018] The outer casing of the device is also secured with a cover plate by screws, which isolates and protects each feeler gauge.

[0026] like Figure 1-4 As shown, a rapid inspection device for elevator brake clearance includes a guide mechanism 1, with a measuring mechanism 2 installed inside the guide mechanism 1. The guide mechanism 1 includes a housing 101, with a mounting groove 102 on one side of the housing 101. Several threaded holes 103 are formed at the edge of the mounting groove 102, and a cover plate 107 is movably mounted inside the mounting groove 102. A connecting screw passes through the surface of the cover plate 107 near each threaded hole 103, and each screw is threaded into the threaded hole 103. Slide grooves 108 are formed in the middle and on the upper and lower sides of the surface of the cover plate 107, extending horizontally. A slider 110 is slidably connected inside each slide groove 108. A shaft 112 is fixedly connected to the side of the slider 110 closest to the inside of the housing 101, and a push plate 111 is fixedly connected to the side of the slider 110 furthest from the shaft 112. Figure 1 , Figure 3 As shown, by removing each screw with a screwdriver, the cover plate 107 can be separated from the inside of the mounting groove 102, thus facilitating the replacement of each feeler gauge.

[0027] Each slide groove 108 has a magnetic block 109 fixedly connected to both sides of its inner wall, and the outer wall of the magnetic block 109 is also magnetically connected to the slider 110, such as... Figure 1 As shown, the slider 110 is made of iron and can be attracted to the magnetic block 109. After the slider 110 is attracted to the magnetic block 109, it is convenient to position the feeler gauge.

[0028] A lubrication port 104 is also provided on the top side of the outer casing 101. A dust plug 105 is engaged inside the lubrication port 104. A strap is fixed to the top side of the dust plug 105, and the other end of the strap is fixedly connected to the outer casing 101. Figure 3 As shown, the dust plug 105 is made of silicone and can seal the lubrication port 104 to prevent dust from entering through the lubrication port 104;

[0029] The outer casing 101 is fixedly connected to a handle 106 on the side away from the dust plug 105.

[0030] The measuring mechanism 2 includes a feeler gauge 1 201. A feeler gauge 202 is slidably connected to one side of feeler gauge 1 201. A feeler gauge 3 203 is also slidably connected to the side of feeler gauge 202 away from feeler gauge 1 201. A sleeve 1 204 is fixedly connected to the lower inner end of feeler gauge 1 201.

Feeler gauges 1 201, 2 202, and 3 203 are all slidably connected along the inner side of the outer casing 101. Sleeves 1 204, 2 205, and 3 206 are respectively inserted into each insert shaft 112. Figures 1-4 As shown, by moving each push plate 111, different feeler gauges can be moved and extended within the housing 101.

[0031] The working principle of this utility model:

[0032] When the device is in use, by pushing the bottom push plate 111, the slider 110 moves along the inside of the slide groove 108. The bottom insertion shaft 112 pushes the insertion sleeve 204 to move, so that the feeler gauge 201 can move along the inside of the outer shell 101. Then, the end of the feeler gauge 201 can extend out of the outer shell and be inserted into the gap of the elevator brake. According to the above, push the slider 110 one by one, so as to drive the feeler gauge 202 or feeler gauge 303 to extend out of the outer shell until the gap of the elevator brake is filled. Finally, the width of the gap of the elevator brake is obtained according to the number of feelers in the gap.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
