Description

Technical Field

[0001] The utility model relates to a construction trolley for bridge guardrails and tunnel gutter cable troughs. Background Art

[0002] Currently, during the construction of bridge and tunnel projects, the construction of bridge guardrails and tunnel gutter cable troughs is a crucial part. These structures not only relate to the safety of the project but also directly affect the convenience of subsequent use and the difficulty of maintenance. However, traditional construction trolleys often have many deficiencies, especially in terms of construction flexibility. Traditional construction trolleys are unable to cope well with construction requirements at different angles and heights. For example, a new type of auxiliary platform for bridge anti-collision guardrail construction disclosed in the patent application number 202111214444.1. Since the installation positions of bridge guardrails are diverse, operations may be required on the sides, tops, or even inclined surfaces of the bridge, and the construction of tunnel gutter cable troughs often needs to be carried out in narrow and complex spaces. Traditional construction equipment often has difficulty adapting to these changing construction environments, resulting in low construction efficiency and even being unable to complete construction tasks. Content of the Utility Model

[0003] Therefore, in view of the above problems, the utility model proposes a construction trolley for bridge guardrails and tunnel gutter cable troughs.

[0004] To achieve the above object, the utility model adopts the following technical solutions: A construction trolley for bridge guardrails and tunnel gutter cable troughs, including a trolley chassis and front wheels and rear wheels provided on the trolley chassis. Two lifting devices, a hydraulic pump station, and counterweights are arranged on the trolley chassis. The bottoms of the two lifting devices are provided on the trolley chassis through slewing bearings. The lifting device includes a fixed arm and a telescopic arm hinged to the upper end of the fixed arm through a telescopic oil cylinder. The telescopic arm and the telescopic oil cylinder are controlled to extend and retract by the hydraulic pump station.

[0005] Further improvement: A hoisting structure is provided on the lifting device, including a pulley and a rope body fixer provided at the free end of the telescopic arm. A hanging wheel and a hook are provided below the pulley. A winch is provided on the fixed arm. A steel wire rope is fixed on the rope body fixer. The free end of the steel wire rope sequentially bypasses the hanging wheel and the pulley and then is connected to the winch.

[0006] Further improvement: A formwork installation structure is provided on the lifting device. The telescopic arm includes an outer arm and an inner arm. The formwork installation structure includes telescopic rods respectively hinged to the free ends of the outer arm and the inner arm. The free end of the telescopic rod is hinged with a cable trough formwork. The telescopic rod is controlled to extend and retract by the hydraulic pump station.

[0007] Further improvement: The hydraulic pump station is arranged between the two lifting devices. There are two counterweights, which are arranged on both sides of the hydraulic pump station.

[0008] Further improvement is made such that the front wheels are steering wheels and are controlled to rotate by a hydraulic pump station, and the rear wheels are driving wheels and are controlled to move by the hydraulic pump station.

[0009] By adopting the foregoing technical solution, the beneficial effects of the present utility model are as follows: The hoisting device of the present utility model is installed on the chassis trolley through a slewing bearing, enabling the hoisting device to flexibly turn and adapt to construction requirements at different angles. The fixed arm and telescopic arm structures in the hoisting device enable it to be applicable to construction requirements of different heights and widths, greatly broadening the construction scope. The setting of the counterweight ensures the balance and safety of the trolley during construction operations. Description of the Drawings

Detailed Embodiments

[0015] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0016] Embodiment 1

[0017] Referring to Figure 1-2 , the first embodiment provides a construction trolley for bridge guardrails and tunnel drainage cable troughs, including a trolley chassis 1 and front wheels 2 and rear wheels 3 provided on the trolley chassis 1. Two hoisting devices, a hydraulic pump station 5, and a counterweight 6 are arranged on the trolley chassis 1. Among them, the front wheels 2 are steering wheels and are controlled to rotate by the hydraulic pump station 5, the rear wheels 3 are driving wheels and are controlled to move by the hydraulic pump station 5. The hydraulic pump station 5 is arranged between the two hoisting devices. There are two counterweights 6 and they are arranged on both sides of the hydraulic pump station 5.

[0018] In this embodiment, the bottoms of the two lifting devices are provided on the trolley chassis 1 through a slewing bearing, enabling the lifting devices to rotate 360°. The lifting device includes a fixed arm 41 and a telescopic arm 42 hinged to the upper end of the fixed arm 41 through a telescopic oil cylinder 43. The telescopic arm 42 and the telescopic oil cylinder are both controlled by a hydraulic pump station 5 for telescoping. A hoisting structure 7 is provided on the lifting device, including a pulley 71 and a rope fixator 72 provided at the free end of the telescopic arm 42. A hanging wheel 73 and a hook 74 are provided below the pulley 71. A winch 76 is provided on the fixed arm 41. A steel wire rope 75 is fixed to the rope fixator 72. The free end of the steel wire rope 75 sequentially bypasses the hanging wheel 73 and the pulley 71 and then is connected to the winch 76.

[0019] When the utility model is in use, one of the lifting devices hoists the formwork of the guardrail 200, and the other lifting device hoists a hanging basket. People can stand in the hanging basket to cooperate in the construction of the bridge guardrail 200.

[0020] The utility model installs the lifting device on the chassis trolley through a slewing bearing, enabling the lifting device to turn flexibly and adapt to the construction requirements at different angles. The structures of the fixed arm 41 and the telescopic arm 42 in the lifting device enable it to be applicable to the construction requirements of different heights and widths, greatly broadening the construction scope. The setting of the counterweight 6 ensures the balance and safety of the trolley during the construction operation.

[0021] Embodiment 2

[0022] Reference Figure 3 , this Embodiment 2 provides a construction trolley for bridge guardrails 200 and tunnel gutter cable troughs that belongs to the same inventive concept as Embodiment 1. The difference between it and Embodiment 1 is that: a formwork installation structure is used to replace the hoisting structure. Among them, the telescopic arm 42 includes an outer arm 421 and an inner arm 422. The formwork installation structure includes telescopic rods 8 respectively hinged to the free ends of the outer arm 421 and the inner arm 422. The free end of the telescopic rod 8 is hinged with a cable trough formwork 300. The telescopic rod 8 is controlled by the hydraulic pump station 5 for telescoping.

[0023] When in use, the two lifting devices hoist the cable trough formwork 300 in parallel through the formwork installation structure, adjust the position of the cable trough formwork 300 through the lifting device, and then finely adjust the position of the cable trough formwork 300 through the telescopic rod 8 to ensure the construction accuracy and quality for pouring concrete.

[0024] Although the utility model is specifically shown and introduced in combination with the preferred implementation scheme, those skilled in the art should understand that various changes can be made to the utility model in terms of form and details without departing from the spirit and scope of the utility model defined by the appended claims, and all are within the protection scope of the utility model.
