Description

Technical Field

[0001] The utility model relates to the technical field of communication engineering construction, in particular to a climbing ladder for communication construction. Background Art

[0002] Communication engineering is developed from the mutual penetration and complementation of wired and wireless communications, electronic technology, postal and telecommunications, etc. Communication engineering requires the establishment of base stations to achieve signal coverage and to communicate and transmit information through signals. Communication engineering construction refers to the process of transforming the design, installation, commissioning and maintenance of communication systems into actual engineering. During the construction and subsequent maintenance of communication engineering, operators are often required to climb high. The most commonly used tool for climbing is a ladder.

[0003] A Chinese utility model patent with publication number CN215718399U discloses a climbing ladder for communication engineering, including a fixed ladder body, a telescopic ladder body, a locking pin and a fixed base. The telescopic ladder body can be extended and retracted relative to the fixed ladder body, thereby adjusting the length of the entire ladder, facilitating transportation while meeting climbing requirements. The fixed base can strengthen the connection between the fixed ladder body and the ground.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the climbing ladder in the above-mentioned patent is not stable enough when placed against a utility pole and is prone to sliding to the left or right and falling, posing certain safety hazards. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a climbing ladder for communication construction.

[0006] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a climbing ladder for communication construction, comprising a climbing ladder body, wherein a fixing plate is fixed on the upper end of the climbing ladder body, and the side wall of the fixing plate is rotatably connected to a rotating seat, and the side wall of the rotating seat is fixed with a mounting seat, and a side wall of the mounting seat away from the rotating seat is provided with a sliding groove, and the inner wall of the sliding groove is rotatably connected to a double-headed screw rod, and the double-headed screw rod is provided with two sections of threads with equal pitches and opposite rotation directions, and the double-headed screw rod is sleeved with a mounting block slidingly connected to the inner wall of the sliding groove, and the mounting blocks are symmetrically provided with two, and the two mounting blocks are respectively threadedly connected to the two sections of threads on the double-headed screw rod, and the side wall of the mounting seat is provided with two symmetrically arranged arc plates, and the two arc plates are respectively fixed to the two side walls of the mounting blocks, and a driving component for driving the double-headed screw rod to rotate is installed on the mounting seat.

[0007] By adopting the above technical scheme, when it is necessary to fix the climbing ladder body on the utility pole, the staff will place the climbing ladder body against the utility pole so that the utility pole is between the two arc-shaped plates, and then drive the double-headed screw to rotate through the driving assembly. Since the two mounting blocks are threadedly connected to the two sections of threads on the double-headed screw, and the mounting blocks are slidingly connected to the slide grooves, the two mounting blocks are moved closer to each other, and drive the two arc-shaped plates to move and press against the utility pole, which has a fixed and limited effect on the climbing ladder body, enhances the stability of the climbing ladder body, reduces the possibility of the climbing ladder body sliding left and right or even falling, and improves the safety of the climbing ladder body.

[0008] Furthermore, the driving assembly includes a driven bevel gear fixedly mounted on the double-headed screw, a vertical rod penetrating the mounting seat and rotatably connected thereto, an active bevel gear fixed to the lower end of the vertical rod and meshing with the driven bevel gear, and a star-shaped handle fixed to the upper end of the vertical rod.

[0009] By adopting the above technical solution, when the double-headed screw needs to be rotated, the staff only needs to rotate the vertical rod and the active bevel gear through the star-shaped handle. Since the active bevel gear is meshed with the driven bevel gear, and the driven bevel gear is fixedly sleeved on the double-headed screw, the double-headed screw can be rotated, which facilitates the movement of the mounting block and the arc plate.

[0010] Furthermore, a limiting assembly for limiting the position of the vertical rod is installed on the vertical rod, and the limiting assembly includes a limiting nut sleeved on the vertical rod and threadedly connected.

[0011] By adopting the above technical solution, when the arc plate is pressed against the electric pole, the staff needs to tighten the limit nut so that the lower surface of the limit nut presses against the upper surface of the mounting seat, thereby limiting the vertical pole and reducing the probability of the arc plate moving due to automatic rotation of the vertical pole.

[0012] Furthermore, an annular rubber sheet is sleeved on the vertical rod and is located between the limiting nut and the mounting seat.

[0013] By adopting the above technical solution, the annular rubber sheet is made of rubber material, and its surface has a large friction coefficient. The lower surface of the limit nut cooperates with the upper surface of the mounting seat and presses against the annular rubber sheet, thereby increasing the friction between the lower surface of the limit nut and the upper surface of the mounting seat, reducing the probability of the limit nut rotating, and enhancing the limiting effect on the vertical rod.

[0014] Furthermore, arc-shaped rubber sheets are fixed to the arc-shaped inner walls of the two arc-shaped plates on the sides close to each other.

[0015] By adopting the above technical solution, the arc-shaped rubber sheet is made of rubber material, and the material has greater friction, which increases the friction between the arc-shaped plate and the electric pole, reduces the probability of displacement of the arc-shaped plate, and in addition, the arc-shaped rubber sheet also reduces the wear of the arc-shaped plate.

[0016] Furthermore, two symmetrically arranged safety buckles are fixed to the side wall of the mounting seat away from the fixing ring.

[0017] By adopting the above technical solution, the staff can hang the safety rope on the safety buckle, thereby reducing the probability of the staff falling while climbing the ladder body.

[0018] Furthermore, a rotating shaft is rotatably connected to the side wall of the climbing ladder body near the bottom, and a fixed block is fixed to the end of the rotating shaft away from the side wall of the climbing ladder body. A reinforcement component is installed on the fixed block, and the reinforcement component includes a threaded rod that is penetrated by the fixed block and threadedly connected, a rotating block fixed to the upper end of the threaded rod, and a reinforcement nail that is rotatably connected to the lower end of the threaded rod.

[0019] By adopting the above technical solution, when the climbing ladder body needs to be fixed, the staff rotates the threaded rod by turning the block, so that the threaded rod moves downward and drives the reinforcement nails to drill into the ground, thereby reinforcing the bottom of the climbing ladder body and further improving the stability of the climbing ladder body.

[0020] Furthermore, a receiving groove for receiving the reinforcing nail is provided at the bottom of the fixing block.

[0021] By adopting the above technical solution, when it is necessary to carry the climbing ladder body, the staff can move the reinforcement nails into the receiving groove by rotating the rotating block, thereby reducing the probability of the reinforcement nails injuring the staff when carrying the climbing ladder body.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In the present application, when it is necessary to fix the climbing ladder body on the electric pole, the staff will place the climbing ladder body against the electric pole so that the electric pole is between the two arc-shaped plates, and then drive the double-headed screw to rotate through the driving assembly. Since the two mounting blocks are threadedly connected with the two sections of threads on the double-headed screw, and the mounting blocks are slidably connected with the slide groove, the two mounting blocks are moved close to each other, and the two arc-shaped plates are driven to move and press against the electric pole, which plays a fixed and limited role on the climbing ladder body, enhances the stability of the climbing ladder body, reduces the possibility of the climbing ladder body sliding to the left and right or even falling, and improves the safety of the climbing ladder body;

[0024] 2. In this application, when the double-headed screw needs to be rotated, the staff only needs to rotate the vertical rod and the active bevel gear through the star-shaped handle. Since the active bevel gear is meshed with the driven bevel gear, and the driven bevel gear is fixedly sleeved on the double-headed screw, the double-headed screw is rotated, which is convenient for moving the position of the mounting block and the arc plate;

[0025] 3. In this application, when the arc plate is pressed against the electric pole, the staff needs to tighten the limit nut so that the lower surface of the limit nut presses against the upper surface of the mounting seat, thereby limiting the vertical pole and reducing the probability of the arc plate moving due to automatic rotation of the vertical pole.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0032] like Figure 1-4 As shown, an embodiment of the present application discloses a climbing ladder for communication construction, including a climbing ladder body 1, a fixed plate 2, a rotating seat 3, a mounting seat 4, a double-headed screw 5, a mounting block 6, an arc plate 7 and a driving assembly 8.

[0033] The climbing ladder body 1 is a climbing ladder body 1 commonly used in the prior art and applicable to the present embodiment. The fixed plate 2 is a plate-like structure, the fixed plate 2 is fixed to the upper end of the climbing ladder, and two fixed plates 2 are symmetrically arranged. The rotating seat 3 is a block-like structure with a U-shaped cross-section, and the rotating seat 3 is rotatably connected to the side wall of the fixed plate 2. The mounting seat 4 is a rectangular parallelepiped structure, the mounting seat 4 is fixed to the side wall of the rotating seat 3, and a slide groove 41 is provided on the side wall of the mounting seat 4 away from the rotating seat 3. The double-headed screw 5 is a horizontally arranged rod-like structure, the double-headed screw 5 is rotatably connected to the inner wall of the slide groove 41, and the double-headed screw 5 is provided with two sections of threads with equal pitch and opposite rotation. The mounting block 6 is a rectangular parallelepiped structure, the mounting block 6 is sleeved on the double-headed screw 5, the mounting block 6 is slidably connected to the inner wall of the slide groove 41, and two mounting blocks 6 are symmetrically arranged, and the two mounting blocks 6 are respectively threadedly connected to the two sections of threads on the double-headed screw 5. The arc plate 7 is a plate-like structure with an arc-shaped cross section. The arc plate 7 is arranged on the side wall of the mounting seat 4 . Two arc plates 7 are symmetrically arranged, and the two arc plates 7 are fixed to the side walls of the two mounting blocks 6 respectively.

[0034] The driving assembly 8 is installed on the mounting seat 4 and is used to drive the double-headed screw 5 to rotate. The driving assembly 8 includes a driven bevel gear 81, a vertical rod 82, an active bevel gear 83 and a star-shaped handle 84. The driven bevel gear 81 is fixedly sleeved on the double-headed screw 5, and the axis of the driven bevel gear 81 coincides with the axis of the double-headed screw 5. The vertical rod 82 is a vertically arranged round rod-shaped structure, and the vertical rod 82 is penetrated and rotatably connected on the mounting seat 4. The active bevel gear 83 is fixed at the lower end of the vertical rod 82, and the active bevel gear 83 is meshed with the driven bevel gear 81, and the axis of the active bevel gear 83 coincides with the axis of the vertical rod 82. The star-shaped handle 84 is fixed at the upper end of the vertical rod 82, and the axis of the star-shaped handle 84 coincides with the axis of the vertical rod 82.

[0035] When it is necessary to fix the climbing ladder body 1 on the telephone pole, the staff will place the climbing ladder body 1 on the telephone pole so that the telephone pole is between the two arc-shaped plates 7, and then rotate the vertical rod 82 and the active bevel gear 83 through the star-shaped handle 84. Since the active bevel gear 83 is meshed with the driven bevel gear 81, and the driven bevel gear 81 is fixedly sleeved on the double-headed screw rod 5, the double-headed screw rod 5 is rotated. Since the two mounting blocks 6 are threadedly connected to the two sections of threads on the double-headed screw rod 5, and the mounting blocks 6 are slidingly connected to the slide groove 41, the two mounting blocks 6 are moved closer to each other, and drive the two arc-shaped plates 7 to move and press against the telephone pole, which has a fixed and limited effect on the climbing ladder body 1, enhances the stability of the climbing ladder body 1, reduces the possibility of the climbing ladder body 1 sliding left and right or even falling, and improves the safety of the climbing ladder body 1.

[0036] In order to reduce the probability of the vertical rod 82 rotating automatically, a limit assembly 9 is installed on the vertical rod 82 to limit the vertical rod 82. The limit assembly 9 includes a limit nut 91 and an annular rubber sheet 92. The limit nut 91 is sleeved on the vertical rod 82 and is threadedly connected to the vertical rod 82, and the axis of the limit nut 91 coincides with the axis of the vertical rod 82. The annular gasket is sleeved on the vertical rod 82, and the annular gasket is located between the limit nut 91 and the mounting seat 4. When the arc plate 7 is pressed against the electric pole, the staff needs to tighten the limit nut 91 so that the lower surface of the limit nut 91 cooperates with the upper surface of the mounting seat 4 and presses against the annular rubber sheet 92, thereby limiting the vertical rod 82, thereby reducing the probability of the vertical rod 82 automatically rotating and causing the arc plate 7 to move. The annular rubber sheet 92 is made of rubber material, and its surface has a large friction coefficient, which increases the friction between the lower surface of the limit nut 91 and the upper surface of the mounting seat 4, reduces the probability of the limit nut 91 rotating, and enhances the limiting effect on the vertical rod 82.

[0037] In order to reduce the probability of displacement of the arc plate 7, an arc-shaped rubber sheet 10 is fixed to the arc-shaped inner wall on the side where the two arc plates 7 are close to each other. The arc-shaped rubber sheet 10 is made of rubber material, and its material has a large friction force, which increases the friction force between the arc plate 7 and the electric pole, thereby reducing the probability of displacement of the arc plate 7. In addition, the arc-shaped rubber sheet 10 also reduces the wear of the arc plate 7.

[0038] In order to reduce the probability of workers falling on the climbing ladder body 1, two symmetrically arranged safety buckles 11 are fixed to the side wall of the mounting seat 4 away from the fixing ring. Workers can hang safety ropes on the safety buckles 11, thereby reducing the probability of workers falling on the climbing ladder body 1.

[0039] In order to further improve the stability of the climbing ladder body 1, a rotating shaft 12 is rotatably connected to the side wall of the climbing ladder body 1 near the bottom, and a fixed block 13 is fixed to one end of the rotating shaft 12 away from the side wall of the climbing ladder body 1. A reinforcement assembly 14 is installed on the fixed block 13, and the reinforcement assembly 14 includes a threaded rod 141, a rotating block 142 and a reinforcing nail 143. The threaded rod 141 is a vertically arranged rod-shaped structure, and the threaded rod 141 is penetrated and arranged on the fixed block 13 and is threadedly connected. The rotating block 142 is a round block-shaped structure, and the rotating block 142 is fixed to the upper end of the threaded rod 141, and the axis of the rotating block 142 coincides with the axis of the threaded rod 141. The reinforcing nail 143 is rotatably connected to the lower end of the threaded rod 141, and the axis of the reinforcing nail 143 coincides with the axis of the threaded rod 141. When the climbing ladder body 1 needs to be fixed, the staff rotates the threaded rod 141 by turning the block 142, so that the threaded rod 141 moves downward and drives the reinforcing nails 143 to drill into the ground, thereby reinforcing the bottom of the climbing ladder body 1, thereby further improving the stability of the climbing ladder body 1.

[0040] In order to reduce the probability of the reinforcement nail 143 injuring the staff when carrying the climbing ladder body 1, a receiving groove 131 for accommodating the reinforcement nail 143 is opened at the bottom of the fixed block 13. When the climbing ladder body 1 needs to be carried, the staff moves the reinforcement nail 143 into the receiving groove 131 by rotating the rotating block 142, thereby reducing the probability of the reinforcement nail 143 injuring the staff when carrying the climbing ladder body 1.

[0041] The working principle of a climbing ladder for communication construction in the present embodiment is as follows: when it is necessary to fix the climbing ladder body 1 on the electric pole, the staff puts the climbing ladder body 1 on the electric pole so that the electric pole is between the two arc plates 7, and then rotates the vertical rod 82 and the active bevel gear 83 through the star-shaped handle 84. Since the active bevel gear 83 is meshed with the driven bevel gear 81, the driven bevel gear 81 is fixedly sleeved on the double-headed screw rod 5, so that the double-headed screw rod 5 rotates. Since the two mounting blocks 6 are threadedly connected with the two sections of threads on the double-headed screw rod 5, the mounting blocks 6 are slidably connected with the slide groove 41, so that the two mounting blocks 6 are moved closer to each other, and drive the two arc plates 7 to move and press against the electric pole, which plays a fixing and limiting role on the climbing ladder body 1, enhances the stability of the climbing ladder body 1, reduces the situation where the climbing ladder body 1 slides to the left or right or even falls, and improves the safety of the climbing ladder body 1.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
