Description

A protective device for construction access on a cap beam Technical Field

[0001] This utility model relates to the field of bridge construction technology; specifically, it relates to a protective device for construction access on a cap beam. Background Technology

[0002] Traditionally, the construction of the paving stones and blocks on the cap beams involves simultaneous construction on both beams. This requires the erection of safety ladders at both beams for workers to ascend and descend, and to move between the two beams. During construction, workers first gather on one beam to weld and tie reinforcing bars and install formwork. Then, using the ladders, workers transport equipment across the ground to the second beam for further work. Concrete pouring also necessitates the transfer of personnel and equipment between the two beams via ground-level movement, thus increasing construction time. Due to the extended periods of working at height and unsafe human behavior, workers are prone to using makeshift planks or jumping to move between the two beams, posing significant safety hazards. Summary of the Invention

[0003] In view of this, the present invention provides a protective device for construction passages on cap beams, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0004] To achieve the aforementioned objectives, this utility model provides a protective device for a construction passage on a cap beam, comprising a base frame, a base, and guardrails. The two ends of the base frame overlap between the tops of the opposite ends of two adjacent cap beams. The guardrails are disposed on both sides of the top of the base frame. The base is disposed in the middle of the base frame and between the guardrails on both sides. The base includes a rotating belt and a locking structure. The rotating belt is rotatably mounted on the base frame, and the locking structure is disposed between the base frame and the rotating belt, capable of locking the rotating belt.

[0005] In the aforementioned protective device for construction passages on a cap beam, optionally, a plurality of rotatable rollers are arranged at intervals along the length of the base frame. Each end of the roller is provided with a ring of teeth. Both sides of the inner surface of the rotating belt are provided with tooth grooves that mesh with the teeth. The locking structure is a toothed plate fixedly mounted on the base frame and located inside the rotating belt, with the teeth of the toothed plate facing upwards. The rollers are vertically mounted on the base frame, and the tooth grooves mesh with the toothed plate by the downward displacement of the rollers.

[0006] In the aforementioned protective device for construction passage on a cap beam, optionally, a column sleeve is rotatably sleeved in the middle of the roller, and the upper and lower ends of two adjacent column sleeves are connected by a synchronous plate. The outer surface of the synchronous plate is in contact with the inner surface of the rotating belt, and when the tooth groove meshes with the tooth plate, the upper surface of the tooth plate is in contact with the lower surface of the synchronous plate located above.

[0007] In the aforementioned protective device for construction passages on a cap beam, optionally, a lifting block is sleeved on the outside of the roller shaft with rollers. The lifting block is slidably installed on the base frame in the height direction. Adjacent lifting blocks are fixedly connected by a connecting plate. An adjusting bolt is threaded through the internal thread of the lifting block located at the end, and the adjusting bolt is rotatably connected to the base frame.

[0008] In the aforementioned protective device for construction passages on a cap beam, optionally, multiple toothed plates are provided, and the toothed plates and rollers are staggered along the length of the base frame. Support plates are fixedly provided at both ends of the bottom of the toothed plates, and the support plates are fixedly connected to the base frame.

[0009] In the aforementioned protective device for construction access on a cap beam, optionally, operating rods are equidistantly arranged at both ends of the outer surface of the rotating belt, allowing workers to drive the rotating belt to rotate by pushing and pulling the operating rods.

[0010] In the construction passage protection device on the cap beam as described above, optionally, side bars are provided at equal intervals along the length of the base frame between the guardrail and the base frame, and the top and bottom ends of the side bars are respectively rotatably engaged with the guardrail and the base frame.

[0011] This utility model has at least the following beneficial effects:

[0012] The construction access protection device for the cap beam proposed in this application can effectively improve the construction efficiency of the top pad stone and stop block of the cap beam compared with the traditional method of erecting safety ladders to go up and down the double cap beams. At the same time, the construction personnel can move freely between the two cap beams through this device, which can reduce the equipment handling time, reduce the time of high-altitude operation, and minimize the risk of high-altitude operation.

[0013] The construction access protection device on the cap beam of this application can be applied to the protection of construction access between cap beams of separated bridge piers, which improves construction efficiency, reduces costs, and minimizes construction safety risks.

Detailed Implementation

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] As shown in Figures 1 to 13, this embodiment provides a protective device for a construction passage on a cap beam, including a base frame 1, a base and guardrails 2. The two ends of the base frame 1 overlap between the tops of the opposite ends of two adjacent cap beams. The guardrails 2 are set on the top two sides of the base frame 1. The base is set in the middle of the base frame 1 and between the guardrails 2 on both sides. The base includes a rotating belt 3 and a locking structure 4. The rotating belt 3 is rotatably installed on the base frame 1. The locking structure 4 is set between the base frame 1 and the rotating belt 3 and can lock the rotating belt 3.

[0031] Specifically, the length of the base frame 1 can be increased according to the project requirements. When in use, it can be lifted by a crane between the two cap beams to achieve safe passage conditions for personnel and equipment between the cap beams.

[0032] When the locking structure 4 locks the rotary belt 3, workers can walk directly on the construction passage protection device to carry out the required construction work. When transferring equipment or materials, the rotary belt 3 separates from the locking structure 4, allowing the rotary belt 3 to rotate. Equipment or materials can then be placed directly on the rotary belt 3, and the rotation of the rotary belt 3 enables the transfer of equipment and materials without the need for frequent manual back-and-forth movement between the two cap beams, greatly improving construction efficiency and safety.

[0033] In this embodiment, a plurality of rotatable belt rollers 5 are arranged at intervals along the length direction on the base frame 1. Each end of the belt roller 5 is provided with a ring of teeth 6. Both sides of the inner surface of the rotary belt 3 are provided with tooth grooves 7 that mesh with the teeth 6. The locking structure 4 is a toothed plate fixedly installed on the base frame 1 and located inside the rotary belt 3, with the teeth of the toothed plate facing upward. The belt rollers 5 are vertically mounted on the base frame 1, and the belt rollers 5 are displaced downward so that the tooth grooves 7 mesh with the toothed plate.

[0034] By engaging the tooth pressure of the belt roller 5 with the tooth groove 7 on the rotary belt 3, the rotary belt 3 can ensure that its rotation state is consistent and will not slip through the cooperation of multiple belt rollers 5. At the same time, the multiple belt rollers 5 support the rotary belt 3 at equal intervals, which makes it more stable and can improve the service life of the rotary belt 3.

[0035] When the belt roller 5 moves downward, the rotary belt 3 carried by the belt roller 5 moves downward along with the belt roller 5. When the toothed groove 7 on the rotary belt 3 engages with the toothed plate, the toothed plate can lock the rotary belt 3. At this time, the toothed plate is supported on the bottom of the belt body above the rotary belt 3, so that the rotary belt 3 has stronger stability and improves construction safety during the worker's walking on the rotary belt 3.

[0036] Furthermore, a sleeve 8 is rotatably fitted in the middle of the belt roller 5. The upper and lower ends of two adjacent sleeves 8 are connected by a timing plate 9. The outer surface of the timing plate 9 is in contact with the inner surface of the rotary belt 3, and when the toothed groove 7 meshes with the toothed plate, the upper surface of the toothed plate is in contact with the lower surface of the timing plate 9 located above it. The sleeve 8, in conjunction with the timing plate 9, not only connects all the belt rollers 5 into a relatively complete whole with sufficient stability and strength, but also always supports the inner surface of the rotary belt 3, providing a solidifying and supporting function for the rotary belt 3. This disperses the pressure on the rotary belt 3, prevents deformation of the rotary belt 3, and improves the compressive strength of the rotary belt 3, thereby enhancing its stability and construction safety.

[0037] Furthermore, a lifting block 10 is sleeved on the outside of the roller shaft of the roller 5. The lifting block 10 is slidably mounted on the base frame 1 in the height direction. Two adjacent lifting blocks 10 are fixedly connected by a connecting plate 11. An adjusting bolt 12 is threaded through the internal thread of the lifting block 10 located at the end, and the adjusting bolt 12 is rotatably connected to the base frame 1.

[0038] The lifting block 10 mounts the rollers on the base frame 1 in a way that allows them to rise and fall. Through the connecting plate 11, all the belt rollers 5 can rise and fall synchronously, thereby maintaining the balanced rise and fall of the rotary belt 3. The rise and fall of the rotary belt 3 can be controlled by rotating the adjusting bolt 12. In addition, the adjusting bolt 12 can be used to lock the lifting block 10 located at the end to lock the rotary belt 3 in the height direction.

[0039] Multiple toothed plates are provided, and the toothed plates and belt rollers 5 are staggered along the length of the base frame 1. Support plates 13 are fixedly installed at both ends of the bottom of each toothed plate, and the support plates 13 are fixedly connected to the base frame 1. Specifically, the belt rollers 5 and toothed plates are positioned close together, allowing the belt rollers 5 and toothed plates to essentially cover the upper part of the return belt, thereby improving the support for the rotary belt 3. Furthermore, when a worker walks on the rotary belt 3, pressure is applied to the rotary belt 3, causing the tooth grooves 7 on the rotary belt 3 to mesh more tightly with the toothed plates, keeping the rotary belt 3 stably locked.

[0040] Operating levers 14 are equidistantly arranged at both ends of the outer surface of the rotary belt 3. Workers can drive the rotary belt 3 to rotate by pushing and pulling the operating levers 14. By setting the operating levers 14, the rotation of the rotary belt 3 can be directly controlled manually without the need for additional external power or transmission devices. This simplifies the structure of the construction passage protection device on the cap beam and improves its practicality.

[0041] Side bars 15 are equidistantly arranged between the guardrail 2 and the base frame 1 along the length of the base frame 1, and the top and bottom ends of the side bars 15 are rotatably engaged with the guardrail 2 and the base frame 1, respectively. By setting the side bars 15, when the rotary belt 3 rotates to transfer equipment and materials, especially when transferring materials, after the material shifts laterally and comes into contact with the side bars 15, the side bars 15 can rotate on their own to facilitate smoother passage of equipment and materials, thus improving throughput.

[0042] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
