Description

Technical Field

[0001] This utility model relates to the field of trolley equipment technology, specifically a mobile waterproof canopy trolley for high-speed railway box girders. Background Technology

[0002] With the rapid development of my country's high-speed railway network, bridge engineering accounts for a large proportion, including a significant amount of precast box girder structures. To ensure the construction quality of box girders, improve production efficiency, and enable all-weather, all-season construction, mobile canopy trolleys have become one of the key pieces of equipment in modern precast beam yards. This type of equipment provides a controllable local environment for processes such as rebar tying, concrete pouring, and steam curing of box girders by erecting a movable canopy structure above the precast platform.

[0003] In existing technologies, mobile rain shelter trolleys mainly focus on the basic functions of rain protection and heat insulation. However, in the actual construction of high-standard high-speed railway box girders, especially in summer or in areas and seasons with strong sunlight, traditional rain shelters have revealed the following obvious defects, affecting the precision of construction and the working environment of workers: Conventional awnings typically use a single layer of color steel plate or fixed light-transmitting material (such as polycarbonate sheet) as the roof, which cannot flexibly adjust the lighting inside the awning according to the needs of the construction process.

[0004] Meanwhile, the construction site is dusty, and a lot of dust and mud will accumulate on the top of the canopy after long-term use, which seriously affects the light transmission efficiency of the light-transmitting materials and causes the light transmittance of the canopy surface to decrease over time. This not only affects the lighting conditions inside the canopy, but also accelerates the aging of the materials.

[0005] Therefore, developing a mobile rain shelter trolley that is effective in waterproofing, can regulate light, and is easy to clean and maintain, thereby comprehensively improving the quality assurance capability and working environment comfort of box girder construction, has an urgent practical need and significant engineering application value. This utility model is proposed to address the shortcomings of the existing technology mentioned above. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] participate Figures 1-4As shown, this utility model provides a mobile waterproof canopy trolley for high-speed railway box girders, including a trolley frame 1, a transparent canopy 2 fixedly installed on the top of the trolley frame 1, a canopy cloth 8, two canopy cloth winding devices 3, and two cleaning devices 4. The canopy cloth 8 covers the transparent canopy 2, and the two ends of the canopy cloth 8 are respectively composed of a light-blocking cloth and a light-transmitting cloth towards the center. The two canopy cloth winding devices 3 are respectively fixedly installed at the two ends of the upper part of the trolley frame 1, and are used to wind up the light-blocking cloth and the light-transmitting cloth respectively. The two cleaning devices 4 are respectively fixedly installed at the two ends of the transparent canopy 2, and are used to clean the light-blocking cloth and the light-transmitting cloth respectively. A water tank 7 is fixedly installed on one side of the trolley frame 1, and the water tank 7 is used to supply water to the cleaning devices 4.

[0020] In this embodiment, the fabric winding device 3 includes a winding box 31, a motor 32, a rotating shaft 33, and a winding sleeve 34. The winding box 31 is fixedly installed on the trolley frame 1. The rotating shaft 33 is rotatably installed inside the winding box 31 through a bearing seat. The winding sleeve 34 is sleeved on the surface of the rotating shaft 33. The winding sleeve 34 and the rotating shaft 33 are connected by an elastic buffer. The motor 32 is fixedly installed outside the winding box 31. The output shaft of the motor 32 is inserted into the winding box 31 and fixedly connected to one end of the rotating shaft 33. One end of the fabric 8 is inserted into the winding box 31 and wound around the winding sleeve 34.

[0021] In this embodiment, the cleaning device 4 includes a cleaning box 41, which is fixedly installed at the end of the transparent canopy 2. The cleaning box 41 has a cleaning chamber that runs through both sides. The top and bottom of the cleaning chamber are equipped with a nozzle 45 and a U-shaped frame 42. A pressure roller 43 is rotatably installed in the opening of the U-shaped frame 42. The two pressure rollers 43 are used to roll and clamp the canopy cloth 8. The cleaning box 41 has a water chamber 44 that communicates with the nozzle 45. The water tank 7 is connected to the water tank 44 through a water pipe 71.

[0022] When the two motors 32 start suddenly, the tension on the fabric 8 is reduced to prevent damage to the fabric 8. In this embodiment, the elastic buffer includes two sliding rods 37. The surface of the rotating shaft 33 is symmetrically provided with two protrusions 35. The inner wall of the winding sleeve 34 is symmetrically provided with two arc-shaped grooves 36. The protrusions 35 are inserted into the corresponding arc-shaped grooves 36. The two sliding rods 37 are respectively fixedly installed in the arc-shaped grooves 36. The sliding rods 37 pass through the corresponding protrusions 35, and springs 37 are sleeved at both ends of the sliding rods 37. The springs 37 can provide buffering force. When the motor 32 starts, the rotating shaft 33 immediately rotates, which will squeeze the springs 37. The winding sleeve 34 will only rotate when it reaches the limit position.

[0023] Furthermore, to ensure that the tarpaulin 8 can be moved smoothly by the tarpaulin winding device 3, in this embodiment, a roller 5 is installed on the upper part of the trolley frame 1 between the cleaning device 4 and the tarpaulin winding device 3, and the roller 5 makes rolling contact with the tarpaulin 8.

[0024] In this embodiment, an axial flow fan 6 is fixedly installed on one side of the trolley frame 1, which can blow air to effectively reduce the high temperature during the processing of high-speed railway box girders and increase the comfort of construction workers.

[0025] Furthermore, to ensure that the water tank 7 can supply water to the nozzle 45 smoothly, in this embodiment, a water pump is installed at the bottom of the water tank 7, and the outlet of the water pump is connected to the water pipe 71.

[0026] In this embodiment, the shed fabric 8 is a PVC film, and its light-blocking fabric and light-transmitting fabric are transparent and opaque black, respectively.

[0027] The specific steps are as follows: When shading is needed during the hot summer, simply start the two motors 32, one to roll up and the other to feed the roll, so that the shading cloth of the canopy 8 moves to the surface of the transparent canopy 2 and completely covers the transparent canopy 2, at which point shading can be performed. When light needs to be transmitted on a cloudy day, the two motors 32 are started in the opposite way to move the light-transmitting cloth of the canopy 8 to the surface of the transparent canopy 2, completely covering the transparent canopy 2, thus ensuring that external light can enter. When the tarpaulin needs to be cleaned, simply control the tarpaulin 8 to move back and forth via motor 32, and then supply water to the nozzle 45 through water tank 7. The nozzle 45 can wash away the dust and dirt on the tarpaulin 8.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
