Description

Technical Field

[0001] This utility model belongs to the field of elevator component manufacturing technology, and is particularly related to an elevator guide rail drilling and alignment tool. Background Technology

[0002] Vertical elevators typically consist of a car, elevator guide rails, and a lifting mechanism. The elevator guide rails are installed vertically on both sides of the elevator shaft and slide along the sides of the elevator shaft to prevent swaying during ascent and descent. Figure 4 As shown, elevator guide rails are typically T-shaped structures with two symmetrical bevels on their transverse section. These bevels increase structural strength while reducing steel usage. Multiple sets of connection holes are formed on both bevels for connection to mounting brackets fixed within the elevator shaft. Because the holes in the elevator guide rails are on bevels, the drill bit is prone to slipping when drilling downwards on these bevels, affecting the drilling accuracy. Therefore, improvements are necessary. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides an elevator guide rail drilling and alignment fixture, which can fix the elevator guide rail and perform drilling and alignment through the alignment hole on the push block, and make the drill bit drill in the alignment hole to prevent the drill bit from tilting.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] An elevator guide rail drilling and alignment fixture includes:

[0006] A rectangular support platform has a strip groove along its length in the middle of its top surface to accommodate the elevator guide rail. Vertical plates are provided on both sides of the top of the rectangular support platform.

[0007] Two sets of push blocks are positioned above the rectangular support platform and are symmetrically arranged relative to the strip groove. Each push block has a vertical alignment hole. The ends of the two sets of push blocks away from the strip groove are vertically connected to two sets of guide rods, and the two sets of guide rods are vertically inserted through the two vertical plates.

[0008] A pair of synchronous plates are connected to the ends of two sets of guide rods away from the push block, and the pair of synchronous plates are connected to the two push ends of a bidirectional telescopic mechanism.

[0009] Furthermore, the bidirectional telescopic mechanism includes a first rotating shaft, a pair of first connecting rods, and a rotating mechanism. The first rotating shaft passes through the middle of the rectangular support platform along its length, and both ends of the first rotating shaft pass through the two ends of the rectangular support platform and connect to the middle of the pair of first connecting rods. Both ends of the first connecting rods are hinged to one end of a pair of second connecting rods. Each of the pair of second connecting rods is connected to a second rotating shaft on the side facing the rectangular support platform. The two pairs of second rotating shafts are rotatably connected to both ends of a pair of synchronous plates. The rotating mechanism is connected to the first rotating shaft and is used to drive the first rotating shaft to rotate.

[0010] Furthermore, the rotating mechanism includes a hydraulic cylinder, a rack, and a gear. The gear is coaxially connected to one end of the first rotating shaft, the rack meshes with the gear, and one end of the rack is connected to the movable end of the hydraulic cylinder.

[0011] Furthermore, the bottom of the rectangular support platform is provided with two pairs of support legs along the length direction, and a horizontal plate is provided on the outer side of the pair of support legs near the hydraulic cylinder, and the hydraulic cylinder is fixed on the horizontal plate.

[0012] Furthermore, the bottom surface of the push block is inclined downwards at the end away from the strip groove, and the height of the lowest point of the inclined surface of the elevator guide rail is higher than the height of the top of the strip groove. When the two sets of push blocks abut against the two sides of the vertical section of the elevator guide rail placed in the strip groove, the bottom surface of the two sets of push blocks abuts against the two inclined surfaces of the elevator guide rail respectively.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. It can fix the elevator guide rail and drill through the alignment hole on the push block, and make the drill bit drill in the alignment hole to prevent the drill bit from tilting.

[0015] 2. A single hydraulic cylinder power source can drive two sets of push blocks to simultaneously clamp the elevator guide rail. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0022] This application provides an elevator guide rail drilling and alignment fixture, such as... Figures 1-3 As shown, it includes a rectangular support platform 2, a pusher block 3, a synchronization plate 4, etc.

[0023] Specifically, a strip groove 201 is opened along the length direction in the middle of the top surface of the rectangular support platform 2 to accommodate the elevator guide rail 1. Vertical plates 202 are provided on both sides of the top of the rectangular support platform 2. There are two sets of push blocks 3, both located above the rectangular support platform 2 and symmetrically arranged with respect to the strip groove 201. Each push block 3 has a vertical alignment hole 301. The ends of the two sets of push blocks 3 away from the strip groove 201 are respectively vertically connected to the two sets of guide rods 301. The two sets of guide rods 301 are respectively vertically inserted into the two vertical plates 202. There is a pair of synchronous plates 4, which are respectively connected to the ends of the two sets of guide rods 301 away from the push blocks 3. The pair of synchronous plates 4 are connected to the two pushing ends of a bidirectional telescopic mechanism. Specifically, the pushing direction of the two pushes of the bidirectional telescopic mechanism is parallel to the width direction of the rectangular support platform 2.

[0024] In actual use, the elevator guide rail 1 is placed in the strip groove 201. Then, the two telescopic ends of the bidirectional conveying mechanism are controlled to drive a pair of synchronous plates 4 to move inward synchronously. Then, the guide rod 301 drives two sets of push blocks 3 to abut against the two sides of the vertical section of the elevator guide rail 1, clamping the elevator guide rail 1. At this time, the alignment hole 301 on the push block 3 is directly above the inclined surface 101 of the horizontal section of the elevator guide rail 1. Specifically, the alignment hole 301 can be set to match the position of the connection hole 102 that needs to be opened on the elevator guide rail 1. The drill bit of the drilling equipment can be inserted into the alignment hole 301 to perform drilling. In this way, the drill bit is in the alignment hole 301, which can prevent the drill bit from shaking and tilting, and improve the drilling accuracy.

[0025] For details, please refer to Figure 2 The bottom surface of the push block 3, away from the strip groove 201, is inclined downwards. The lowest point of the inclined surface 101 of the elevator guide rail 1 is higher than the top of the strip groove 201. When the two sets of push blocks 3 abut against the two sides of the vertical section of the elevator guide rail 1 placed in the strip groove 201, the bottom surfaces of the two sets of push blocks 3 abut against the two inclined surfaces 101 of the elevator guide rail 1. This method can increase the contact area between the push block 3 and the elevator guide rail 1, improve the clamping effect on the elevator guide rail 1, and because the two inclined surfaces 101 of the elevator guide rail 1 are abutted by the bottom of the push block 3, there is no gap between them, which can further prevent the drill bit from slipping and tilting during drilling.

[0026] Specifically, a pair of linear mechanisms with opposite extension directions can be selected as a bidirectional extension mechanism. In one embodiment, see [reference needed]. Figure 1 , Figure 3 The bidirectional telescopic mechanism includes a first rotating shaft 5, a pair of first connecting rods 6, and a rotating mechanism. The first rotating shaft 5 passes through the middle of the rectangular support platform 2 along its length, and both ends of the first rotating shaft 5 pass through the two ends of the rectangular support platform 2 and are connected to the middle of the pair of first connecting rods 6. Both ends of the first connecting rods 6 are hinged to one end of a pair of second connecting rods 601. Each of the pair of second connecting rods 601 is connected to a second rotating shaft 602 on the side facing the rectangular support platform 2. The two pairs of second rotating shafts 602 are rotatably connected to the two ends of a pair of synchronous plates 4. The rotating mechanism is connected to the first rotating shaft 5 and is used to drive the first rotating shaft 5 to rotate. When the rotating mechanism drives the first connecting rod 6 to rotate to a horizontal state via the first rotating shaft 5, the distance between the end of the first connecting rod 6 and the first rotating shaft 5 will reach its maximum. The synchronizing plate 4 can be pushed outward via the second rotating shaft 602, and then the push block 3 can be pulled outward via the guide rod 301, thus releasing the clamping of the elevator guide rail 1. When the rotating mechanism drives the first connecting rod 6 to rotate to a preset tilt angle via the first rotating shaft 5, the distance between the end of the first connecting rod 6 and the first rotating shaft 5 will decrease. The synchronizing plate 4 can be pulled inward via the second rotating shaft 602, thus causing the push block 3 to move inward synchronously to clamp the elevator guide rail 1.

[0027] For more details, please refer to Figure 1 , Figure 3 The rotating mechanism includes a hydraulic cylinder 7, a rack 701, and a gear 702. The gear 702 is coaxially connected to one end of the first rotating shaft 5. The rack 701 meshes with the gear 702, and one end of the rack 701 is connected to the movable end of the hydraulic cylinder 7. The bottom of the rectangular support platform 2 has two pairs of support legs 203 along its length. A horizontal plate is provided on the outer side of the pair of support legs 203 near the hydraulic cylinder 7, and the hydraulic cylinder 7 is fixed to the horizontal plate. When the movable end of the hydraulic cylinder 7 is fully extended, the first connecting rod 6 is at a preset tilt angle. When the movable end of the hydraulic cylinder 7 is fully retracted, the first connecting rod 6 is in a horizontal state.

[0028] The above are only some of the embodiments listed in this application and are not intended to limit this application.
