Description

Technical Field

[0001] This utility model relates to the field of front edge plate installation technology, and in particular to an auxiliary device for fixing the front edge plate of an escalator. Background Technology

[0002] The front edge plate of the escalator is installed at the entrance and exit of the escalator to protect the internal equipment of the escalator and support passengers.

[0003] In the prior art, the front edge plate is fixed to the escalator truss with bolts. However, this method is not convenient for adjusting the height and horizontal position of the front edge plate, making it difficult for workers to fix quickly, wasting time and reducing fixing efficiency. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the prior art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary device for fixing the front edge plate of an escalator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary device for fixing the front edge plate of an escalator includes an L-shaped base and a front edge plate body mounted on an escalator truss. The bottom of the L-shaped base has an annular groove, within which a stepped ring is rotatably connected. An annular plate supporting the stepped ring is welded into the annular groove. A threaded sleeve is fixedly connected to the bottom of the stepped ring, and a threaded rod is threadedly connected to the threaded sleeve. A locking component for locking the threaded sleeve is provided on the outer side of the threaded rod. The top of the L-shaped base has a through hole, through which a ball joint is fixedly connected. A rod joint is rotatably connected within the ball joint, and a support plate is fixedly connected to the top of the rod joint. The front edge plate body is disposed on the upper surface of the support plate, and a pressing assembly for fixing the rod joint is provided on the top of the L-shaped base.

[0007] As a further embodiment of this utility model, the locking component is a locking nut, which is threadedly connected to the outside of the threaded rod and located below the threaded sleeve.

[0008] As a further embodiment of this utility model, the extrusion assembly includes two small cylinders, both of which are fixedly connected to the top of the L-shaped base. One end of the telescopic part of each of the two small cylinders is fixedly connected to a connecting block. A clamping sleeve is fixedly connected between the two connecting blocks, and a threaded rod passes through the clamping sleeve. The top of the clamping sleeve is provided with an arc surface that is compatible with the ball joint.

[0009] As a further embodiment of this invention, the two small cylinders are symmetrically distributed on both sides of the through hole.

[0010] As a further embodiment of this utility model, a baffle is fixedly connected to the bottom of the threaded rod, and the diameter of the baffle is larger than the diameter of the threaded rod. Two guide rods are fixedly connected to the bottom of the L-shaped base, and the guide rods pass through the baffle.

[0011] As a further embodiment of this utility model, the bottom of the front edge plate body is fixedly connected with a plurality of uniformly and symmetrically distributed positioning blocks.

[0012] As a further improvement of this utility model, the upper surface of the support plate is provided with a plurality of positioning grooves that cooperate with the positioning blocks.

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

[0014] 1. Through the coordinated use of the threaded rod, rod joint, and ball joint, the threaded rod moves up and down, which drives the support plate to move up and down, thereby changing the height of the front edge plate. At the same time, with the cooperation of the rod joint and ball joint, the support plate can be tilted in a small range, thereby changing the horizontal position of the front edge plate body, making it easier to level the front edge plate and improving the fixing efficiency of the front edge plate.

[0015] 2. By using the positioning block and positioning groove together, when the front edge plate is set on the support plate, the positioning block on the front edge plate is inserted into the positioning groove on the support plate, so that the front edge plate can be quickly and initially positioned, preventing slippage during installation and improving the effectiveness of the auxiliary device.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-7 An auxiliary device for fixing the front edge plate of an escalator includes an L-shaped base 2 and a front edge plate body 3 installed on the escalator truss 1.

[0026] like Figure 7 As shown, an annular groove 19 is provided at the bottom of the L-shaped base 2, and a stepped ring 11 is rotatably connected in the annular groove 19. The cross-section of the stepped ring 11 is an inverted L shape, and an annular plate is welded in the annular groove 19 to support the stepped ring 11.

[0027] like Figure 2 and Figure 4 As shown, a threaded sleeve 12 is welded to the bottom of the stepped ring 11, and a threaded rod 6 is connected to the threaded sleeve 12 internally. A baffle 10 is welded to the bottom end of the threaded rod 6, and the diameter of the baffle 10 is larger than the diameter of the threaded rod 6. Two guide rods are welded to the bottom of the L-shaped base 2, and the guide rods pass through the baffle 10.

[0028] The top of the L-shaped base 2 has a through hole 18. The top of the threaded rod 6 passes through the through hole 18 and is welded with a ball joint 8. A rod joint 7 is rotatably connected inside the ball joint 8. The surface area of ​​the rod joint 7 is more than half of the surface area of ​​the ball joint 8, so that the rod joint 7 will not detach from the inside of the ball joint 8. The ball joint 8 and the rod joint 7 form a rod end ball joint bearing.

[0029] A support plate 4 is welded to the top of the rod joint 7, and the front edge plate body 3 is set on the upper surface of the support plate 4.

[0030] When the height needs to be adjusted, the threaded sleeve 12 is rotated through the stepped ring 11 that rotates in the annular groove 19. At this time, the threaded sleeve 12 will cause the threaded rod 6 to drive the guide rod to move upward through the threaded engagement between the threaded sleeve 12 and the threaded rod 6. The threaded rod 6 will push the support plate 4 to move upward through the ball joint 8 and the rod joint 7. The support plate 4 will push the front edge plate body 3 to move upward, thereby changing the height of the front edge plate body 3.

[0031] When leveling needs to be adjusted, the support plate 4 is tilted slightly in the ball joint 8 via the rod joint 7. The support plate 4 will cause the front plate body 3 to tilt slightly in the ball joint 8, thereby changing the level of the front plate body 3. This can change the height and horizontal position of the front plate body 3, making it easier for the front plate to be leveled and improving the fixing efficiency of the front plate.

[0032] In this utility model, a locking component for locking the threaded sleeve 12 is provided on the outer side of the threaded rod 6. The locking component is a locking nut 5, which is threadedly connected to the outer side of the threaded rod 6. The locking nut 5 is located below the threaded sleeve 12. After the front edge plate body 3 is adjusted to a suitable height, the operator fixes the threaded sleeve 12 with a wrench and then rotates the locking nut 5 to move the locking nut 5 relative to the threaded sleeve 12. This causes the locking nut 5 to squeeze and lock the threaded sleeve 12, thereby locking the threaded rod 6. This provides double insurance and greatly enhances the device's anti-loosening ability under long-term vibration environment, ensuring the long-term reliability of the front edge plate fixation.

[0033] In particular, the top of the L-shaped base 2 is provided with a pressing assembly for fixing the rod joint 7. The pressing assembly includes two small cylinders 17, which move synchronously and have a self-locking function. The cylinders are model SMCCJ2. Both small cylinders 17 are fixed to the top of the L-shaped base 2 by bolts. One end of the telescopic part of each of the two small cylinders 17 is fixed to a connecting block 16 by bolts. A clamping sleeve 9 is welded between the two connecting blocks 16, and the threaded rod 6 passes through the clamping sleeve 9. The top of the clamping sleeve 9 is provided with an arc surface 15 that matches the ball joint 8. Cylinders 17 are symmetrically distributed on both sides of the through hole 18. After the horizontal position of the front edge plate body 3 is adjusted, the small cylinder 17 is activated to extend. The small cylinder 17 pushes the clamping sleeve 9 upward through the connecting block 16, so that the arc surface 15 on the clamping sleeve 9 is in contact with the surface of the ball joint 8 and squeezes the ball joint 8. By forcefully pressing the outer edge of the ball joint 8, this pressure will generate huge friction between the rod joint 7 and the ball joint 8, completely eliminating its rotational freedom and firmly fixing the support plate 4 in the adjusted position, thereby fixing the horizontal position of the front edge plate body 3 after adjustment.

[0034] Multiple evenly and symmetrically distributed positioning blocks 13 are welded to the bottom of the front edge plate body 3. Multiple positioning grooves 14 that cooperate with the positioning blocks 13 are opened on the upper surface of the support plate 4. Through the cooperation of the positioning blocks 13 and the positioning grooves 14, the front edge plate can be quickly and initially positioned to prevent slippage during installation and improve the effectiveness of the auxiliary device.

[0035] Working principle: When height adjustment is required, the threaded sleeve 12 is rotated through the stepped ring 11 rotating within the annular groove 19. At this time, the threaded sleeve 12, through threaded engagement with the threaded rod 6, causes the guide rod to move upward. The threaded rod 6, through the ball joint 8 and rod joint 7, pushes the support plate 4 upward, which in turn pushes the front edge plate body 3 upward, thus changing the height of the front edge plate body 3. After the front edge plate body 3 is adjusted to a suitable height, the operator uses a wrench to fix the threaded sleeve 12 and then rotates the locking nut 5, causing the locking nut 5 to move relative to the threaded sleeve 12. This causes the locking nut 5 to compress and lock the threaded sleeve 12, locking the threaded rod 6, thus providing double insurance and greatly enhancing the device's resistance to loosening under long-term vibration, ensuring the long-term reliability of the front edge plate fixation. When level adjustment is required... When the support plate 4 is tilted slightly within the ball joint 8 via the rod joint 7, the support plate 4 will cause the front plate body 3 to tilt slightly, thereby changing the level of the front plate body 3. Then, the small cylinder 17 is activated to extend. The small cylinder 17 pushes the clamping sleeve 9 upward through the connecting block 16, so that the arc surface 15 on the clamping sleeve 9 is in contact with the surface of the ball joint 8 and squeezes the ball joint 8. By forcefully pressing the outer edge of the ball joint 8, this pressure will generate huge friction between the rod joint 7 and the ball joint 8, completely eliminating its rotational freedom and firmly fixing the support plate 4 in the adjusted position, thereby fixing the adjusted horizontal position of the front plate body 3. This can change the height and horizontal position of the front plate body 3, making it easier to level the front plate and improving the fixing efficiency of the front plate.

[0036] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
