Description

Technical Field

[0001] This utility model relates to the field of rail clamping technology, specifically a rail clamping device for elevator installation and maintenance. Background Technology

[0002] An elevator is a vertical transportation tool, typically consisting of a car, guide rails, traction machine, and control system. Driven by a motor, the car moves up and down along the guide rails, enabling the rapid transport of people or goods between different floors. Widely used in residential buildings, shopping malls, office buildings, and other buildings, elevators are characterized by safety, efficiency, and convenience, and are an indispensable infrastructure for modern high-rise buildings.

[0003] Elevator installation and maintenance are crucial for ensuring safe elevator operation. Maintenance involves regular cleaning and lubrication, component inspection, troubleshooting, and performance testing. A maintenance log should be maintained to record the elevator's operating status, and aging parts should be replaced promptly. Through preventative maintenance and emergency repairs, the elevator is ensured to always operate safely and reliably, extending its lifespan.

[0004] Elevator maintenance often requires the use of rail clamps. Existing clamping devices, after being fixed on both sides of the elevator car, squeeze towards the center with bolts, which can lead to excessive local pressure on the bolts. Therefore, to address the above problem, a rail clamp for elevator installation and maintenance is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An elevator installation and maintenance rail clamp of this utility model includes a fixed frame; a pair of fixed seats are fixedly connected to the inner side wall of the fixed frame; a sliding groove is opened on the side wall of the fixed seat; a top block is slidably connected to the middle of the sliding groove; a pair of support frames are fixedly connected to the inner side wall of the fixed seat; the support frames pass through the fixed seats; an electric push rod is hinged to the top of the support frame; a connecting seat is fixedly connected to the top of the electric push rod; a sleeve-type telescopic rod is opened at the bottom of the fixed seat; a sleeve-type telescopic rod is fixedly connected to the top of the connecting seat; a first groove is hinged to the top of the sleeve-type telescopic rod; by pushing the support frame to drive the sleeve-type telescopic rod to extend or retract, the distance between the top blocks can be quickly adjusted to adapt to elevator guide rails of different widths, reducing the adaptation difficulties caused by differences in guide rail dimensions. The inclined setting of the fixed seats, when the car slides, allows the top blocks to move upward and closely adhere to the side wall, increasing the friction between the top blocks and the guide rail, effectively reducing car movement. When the car slides unexpectedly, this structure allows the fixed seats and top blocks to cooperate to generate a strong braking force.

[0007] Preferably, the side wall of the fixing frame is threaded with bolts; multiple handles are fixed to the top of the bolts; friction pads are fixed to the top of the handles; by rotating the bolts to make the friction pads fit tightly against the side of the guide rail, the clamping force of the fixing frame on the guide rail can be further enhanced, and the applicability of the rail clamp can be expanded, based on the friction force of the top block clamping the guide rail.

[0008] Preferably, a fixing block is fixedly connected to the side wall of the fixing frame; a support rod is fixedly connected to the bottom end of the fixing block; a fixing frame is fixedly connected to the bottom end of the support rod; a second groove is provided at the top end of the fixing block; a protrusion is provided at the top end of the fixing block; by inserting the protrusion into the second groove, the car and the rail clamp can be quickly engaged, reducing alignment operations and facilitating the fixing of the protrusion to the bottom of the car to form a connection with the fixing block.

[0009] Preferably, an elastic cloth is fixed to the side wall of the top block; the elastic cloth is correspondingly arranged with the top block; the elastic cloth can block dust and impurities from entering the interior of the slide groove, reduce foreign objects from getting stuck in the top block, and reduce the friction between the slide groove and the top block, causing the top block to slide unsmoothly in the middle of the slide groove.

[0010] Preferably, multiple sets of flexible magnetic blocks are fixed to the side wall of the top block; the flexible magnetic blocks are arranged in an array on the side wall of the top block; a silicone pad is fixed to the top of the flexible magnetic block; the attraction force of the multiple sets of flexible magnetic blocks can make the top block actively stick to the side wall of the guide rail. When the car shakes, the attraction force of the flexible magnetic blocks helps to fix it, improves the continuous clamping force of the rail clamp on the guide rail, reduces slippage and displacement, and the flexible magnetic blocks can adapt to the micro-fins of the guide rail to ensure uniform distribution of friction.

[0011] Preferably, a cleaning ring is fixed to the side wall of the fixing frame; the cleaning ring is correspondingly arranged with the bolt; by directly contacting the thread of the bolt with the cleaning ring, dust and debris and other contaminants between the thread teeth can be scraped off, reducing bolt jamming caused by impurities and ensuring smooth bolt rotation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5As shown in the embodiment of this utility model, an elevator installation and maintenance rail clamp includes a fixed frame 1; a pair of fixed seats 11 are fixedly connected to the inner side wall of the fixed frame 1; a sliding groove 12 is formed on the side wall of the fixed seat 11; a top block 13 is slidably connected to the middle of the sliding groove 12; a pair of support frames 14 are fixedly connected to the inner side wall of the fixed seat 11; the support frames 14 pass through the fixed seat 11; an electric push rod 15 is hinged to the top of the support frame 14; and a connecting rod is fixedly connected to the top of the electric push rod 15. Seat 16; the bottom end of the fixed seat 11 is provided with a sleeve-type telescopic rod 17; the top end of the connecting seat 16 is fixedly connected to the sleeve-type telescopic rod 17; the top end of the sleeve-type telescopic rod 17 is hinged with a first groove 18; during operation, before the fixed frame 1 is placed as a whole on the clamping guide rail, a pair of support frames 14 can be pushed to drive the sleeve-type telescopic rod 17 to extend. After the support frames 14 are retracted, a pushing force can be applied to the top block 13, pushing the top block 13 to slide in the middle of the slide groove 12, thus fixing the fixed seat 11 as a whole. Move to the middle of the guide rail that needs to be clamped, then push a pair of support frames 14 to retract the sleeve-type telescopic rod 17, pushing the entire fixed frame 1 to the side wall of the guide rail to squeeze and clamp a pair of fixed seats 11 against the side wall of the guide rail. When the car slides, a pair of top blocks 13 move up and press against the side wall fixed seats 11. The inclined setting of the fixed seats 11 will generate stronger friction, restricting the movement of the car. When the fixed seats 11 move, the sleeve-type telescopic rod 17 can extend and retract arbitrarily without affecting the sliding of the top blocks 13 in the slide groove 12. By pushing the support frame 14 to extend or retract the sleeve-type telescopic rod 17, the distance between the top blocks 13 can be quickly adjusted to adapt to elevator guide rails of different widths, reducing the adaptation difficulties caused by differences in guide rail size. The inclined setting of the fixed seats 11, combined with the upward movement of the top blocks 13 against the side wall when the car slides, can increase the friction between the fixed seats and the guide rail, effectively reducing the movement of the car. When the car slides unexpectedly, this structure can generate a strong braking force by cooperating with the fixed seats 11 and the top blocks 13.

[0025] like Figures 1 to 2 As shown, the side wall of the fixing frame 1 is threaded with bolts 2; multiple handles 21 are fixed to the top of the bolts 2; friction pads 22 are fixed to the top of the handles 21; during operation, after the fixing frame 1 is fixed in the middle of the guide rail, the bolts 2 can be rotated to move on the side wall of the fixing frame 1, so that the friction pads 22 are pressed tightly against the side of the guide rail, further clamping the guide rail. The handles 21 make it easier to rotate the bolts 2; by using the friction of the top block 13 to clamp the guide rail, rotating the bolts 2 causes the friction pads 22 to press tightly against the side of the guide rail, which can further enhance the clamping force of the fixing frame 1 on the guide rail and expand the applicability of the rail clamp.

[0026] like Figure 1 and Figure 4As shown, a fixing block 3 is fixedly connected to the side wall of the fixing frame 1; a support rod 31 is fixedly connected to the bottom end of the fixing block 3; a fixing frame 1 is fixedly connected to the bottom end of the support rod 31; a second groove 33 is provided at the top end of the fixing block 3; a protrusion 32 is provided at the top end of the fixing block 3; during operation, the protrusion 32 can be welded to the bottom of the car; when elevator maintenance is required, the protrusion 32 can be inserted into the second groove 33 to form a locking; by inserting the protrusion 32 into the second groove 33, the car and the rail clamp can be quickly locked together, reducing the alignment operation and making it easier to fix the protrusion 32 to the bottom of the car and form a connection with the fixing block 3.

[0027] like Figure 1 and Figure 5 As shown, an elastic cloth 4 is fixed to the side wall of the top block 13; the elastic cloth 4 is correspondingly arranged with the top block 13; during operation, after long-term use, a lot of dust will accumulate inside the slide groove 12. At this time, the elastic cloth 4 can prevent dust from entering the slide groove 12; the elastic cloth 4 can prevent dust and impurities from entering the slide groove 12, reducing foreign objects from getting stuck in the top block 13, which would increase the friction between the slide groove 12 and the top block 13, causing the top block 13 to slide unsmoothly in the middle of the slide groove 12.

[0028] like Figure 1 and Figure 3 As shown, multiple sets of flexible magnetic blocks 5 are fixed to the side wall of the top block 13; the flexible magnetic blocks 5 are arranged in an array on the side wall of the top block 13; a silicone pad 51 is fixed to the top of the flexible magnetic block 5; during operation, the flexible magnetic blocks 5 can be attracted when the top block 13 contacts the side wall of the guide rail, so that the top block 13 is tightly attached to the side wall of the guide rail, and the silicone pad 51 can be spaced between the flexible magnetic blocks 5 and the guide rail; the attraction force of the multiple sets of flexible magnetic blocks 5 can make the top block 13 actively stick to the side wall of the guide rail. When the car shakes, the attraction force of the flexible magnetic blocks 5 assists in fixing, improves the continuous clamping force of the rail clamp on the guide rail, reduces slippage and displacement, and the flexible magnetic blocks 5 can adapt to the micro-strain of the guide rail to ensure uniform distribution of friction.

[0029] like Figures 1 to 2 As shown, a cleaning ring 6 is fixedly connected to the side wall of the fixing frame 1; the cleaning ring 6 is correspondingly arranged with the bolt 2; during operation, when the bolt 2 rotates on the side wall of the fixing frame 1, the cleaning ring 6 can contact the thread in the middle of the bolt 2 to scrape off the contaminants on the surface of the bolt 2; through the direct contact between the cleaning ring 6 and the thread of the bolt 2, dust and debris and other contaminants between the thread teeth can be scraped off, reducing the bolt 2 from getting stuck due to impurities and ensuring the smoothness of the bolt 2 when rotating.

[0030] Working principle: Before the entire fixed frame 1 is placed to clamp the guide rail, a pair of support frames 14 can be pushed to extend the sleeve-type telescopic rod 17. After the support frames 14 are retracted, they can apply a pushing force to the top block 13, pushing the top block 13 to slide in the middle of the slide groove 12, moving the entire fixed seat 11 to the middle of the guide rail to be clamped. Then, the pair of support frames 14 are pushed to retract the sleeve-type telescopic rod 17, pushing the entire fixed frame 1 to the side wall of the guide rail, pressing and clamping the pair of fixed seats 11 against the side wall of the guide rail. When the car slides, the pair of top blocks 13 move upward and press against the side wall fixed seats 11. The inclined setting of the fixed seats 11 will form stronger friction, restricting the movement of the car. When the fixed seats 11 move, the sleeve-type telescopic rod 17 can extend and retract arbitrarily, without affecting the sliding of the top block 13 in the slide groove 12. When the entire fixed frame 1 is fixed to the guide rail, the sliding position is adjusted. After the middle of the rail, the rotatable bolt 2 moves on the side wall of the fixed frame 1, pressing the friction pad 22 tightly against the side of the guide rail, further clamping the guide rail. The handle 21 makes it easier to rotate the bolt 2. The protrusion 32 can be welded to the bottom of the car. When the elevator needs to be inspected, the protrusion 32 can be inserted into the second groove 33 to form a lock. After long-term use, a lot of dust will accumulate inside the slide 12. At this time, the elastic cloth 4 can prevent the dust from entering the slide 12. The flexible magnetic block 5 can be attracted when the top block 13 contacts the side wall of the guide rail, so that the top block 13 is tightly attached to the side wall of the guide rail. The silicone pad 51 can be spaced between the flexible magnetic block 5 and the guide rail. When the bolt 2 rotates on the side wall of the fixed frame 1, the cleaning ring 6 can contact the thread in the middle of the bolt 2 to scrape off the contaminants on the surface of the bolt 2.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
