Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a building construction trolley that facilitates unloading of materials. Background Technology

[0002] Building construction is a systematic project that transforms design drawings into a physical building, mainly comprising five stages: preliminary preparation, foundation construction, main structure, decoration and finishing, and final acceptance. Before construction, geological surveys, drawing review, construction permit applications, and site preparation (including access roads, utilities, and site leveling) must be completed. Foundation construction includes earthwork excavation and ground treatment, such as pile foundations or raft foundations and underground structure construction, with a focus on settlement control. Main structure construction includes reinforced concrete frames, floor slab pouring, and wall construction, emphasizing structural safety and seismic performance.

[0003] Construction trolleys typically consist of a bucket, wheels, and handles, and are used to transport building materials such as sand, gravel, and concrete. However, these trolleys have significant drawbacks in actual use: First, due to the lack of effective securing devices, materials are easily shaken off the edges of the bucket when encountering bumps during transportation, resulting in material waste and on-site pollution; second, unloading requires manual tipping of the bucket or the use of shovels, which is time-consuming and labor-intensive, especially when handling heavy or sticky materials, where efficiency is low. Utility Model Content

[0004] This utility model addresses the problem that materials easily spill from the edges of the truck bed when encountering bumps during transportation, requiring manual tipping or the use of shovels for unloading, which is time-consuming and labor-intensive, especially when handling heavy or sticky materials. To solve the above technical problems, a construction trolley for easy unloading is provided, including a base, a fixed baffle fixedly connected to the top of the base, a fixed column fixedly connected to the inner wall of the fixed baffle, a movable sleeve rotatably connected to the surface of the fixed column, a storage box fixedly connected to the top of the movable sleeve, an installation plate fixedly connected to the top of the base, a fixed column fixedly connected to the surface of the installation plate, a movable sleeve rotatably connected to the surface of the fixed column, a hydraulic telescopic rod fixedly connected to the surface of the movable sleeve, a connecting platform fixedly connected to the output end of the hydraulic telescopic rod, a sliding groove formed on the surface of the fixed baffle, a limit sliding column fixedly connected to the surface of the storage box, and a pusher fixedly connected to the top of the base.

[0005] Through the above technical solution, by setting up a storage box and activating the hydraulic telescopic rod, the output end of the hydraulic telescopic rod extends and retracts towards the connecting platform. When the connecting platform moves forward, it causes the movable sleeve at the bottom of the storage box to rotate on the surface of the fixed column, so that the entire storage box is in a slanted state, which facilitates the unloading of building materials inside the storage box. Through the limiting sliding column, when the storage box rotates and is slanted, the limiting sliding column slides inside the sliding groove, which limits the position of the entire storage box.

[0006] As a further improvement to the above solution, two fixed baffles are provided, which are symmetrically and evenly distributed around the center of the top of the base, and the storage box is located at one end of the two fixed baffles that are close to each other.

[0007] With the above technical solution, two fixed baffles are set and evenly distributed symmetrically around the top center of the base. The storage box is set at one end of the two fixed baffles that are close to each other. The two symmetrically distributed fixed baffles can better protect the storage box from both sides, prevent materials from falling from the side, and improve the protection effect of the materials in the storage box.

[0008] As a further improvement to the above solution, the top of the connecting platform is fixedly connected to the bottom of the storage box, and the limiting slide column passes through the slide groove.

[0009] The top of the connecting platform is fixedly connected to the bottom of the storage box, allowing the hydraulic telescopic rod to effectively control the lifting and lowering of the storage box via the connecting platform. During unloading, the height of the storage box can be adjusted as needed to facilitate smooth material discharge. A limit sliding column penetrates the slide groove, ensuring that the storage box rotates along a predetermined trajectory, preventing instability such as deviation and guaranteeing the accuracy of the unloading operation.

[0010] As a further improvement to the above solution, a limiting sleeve is fixedly connected to the top of the base, a sliding column is slidably connected inside the limiting sleeve, a buffer spring is fixedly connected to the top of the sliding column, and a caster wheel is installed at the bottom of the sliding column.

[0011] Through the above technical solution, a limiting sleeve is fixedly connected to the top of the base, a sliding column is slidably connected inside the limiting sleeve, a buffer spring is fixedly connected to the top of the sliding column, and a universal wheel is installed at the bottom of the sliding column. The structure of the limiting sleeve and the sliding column allows the universal wheel to move up and down within a certain range, and the buffer spring can play a buffering role. When the trolley passes through an uneven road surface, it can reduce the impact of vibration on the trolley and materials, and ensure the smooth operation of the trolley.

[0012] As a further improvement to the above solution, the limiting sleeve is located at the top of the base near the pusher.

[0013] As a further improvement to the above solution, a card platform is fixedly connected to the front of the storage box, a baffle is engaged inside the card platform, and a limit plate is fixedly connected to the front of the baffle.

[0014] The front of the storage box is fixedly connected to a card plate, and a baffle is engaged inside the card plate. The baffle can block the material from the front of the storage box and prevent the material from sliding out of the front of the storage box during transportation. A limit plate is fixedly connected to the front of the baffle and engages with the top of the card plate to further fix the position of the baffle and prevent the baffle from falling out of the card plate due to vibration or other reasons during transportation, thereby enhancing the baffle's blocking effect on the material.

[0015] As a further improvement to the above solution, the limiting plate is snapped onto the top of the card platform.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model, by setting up a storage box and activating a hydraulic telescopic rod, allows the output end of the hydraulic telescopic rod to extend and retract towards the connecting platform. When the connecting platform moves forward, it causes the movable sleeve at the bottom of the storage box to rotate on the surface of the fixed column, so that the entire storage box is in a slanted state, which facilitates the unloading of building materials inside the storage box. Through the limiting sliding column, when the storage box rotates and is slanted, the limiting sliding column slides inside the sliding groove, thus limiting the position of the entire storage box.

[0018] This invention incorporates a buffer spring. When the trolley moves and the casters vibrate, the sliding column compresses the buffer spring, thus cushioning the base at the top of the trolley. Attached Figure Description

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0026] Please combine Figure 1-5 This embodiment of a construction trolley for easy unloading includes a base 1, a fixed baffle 2 fixedly connected to the top of the base 1, a fixed column 3 fixedly connected to the inner wall of the fixed baffle 2, a movable sleeve 4 rotatably connected to the surface of the fixed column 3, a storage box 5 fixedly connected to the top of the movable sleeve 4, an installation plate 6 fixedly connected to the top of the base 1, a fixed column 7 fixedly connected to the surface of the installation plate 6, a movable sleeve 8 rotatably connected to the surface of the fixed column 7, a hydraulic telescopic rod 9 fixedly connected to the surface of the movable sleeve 8, a connecting platform 10 fixedly connected to the output end of the hydraulic telescopic rod 9, a sliding groove 11 opened on the surface of the fixed baffle 2, a limit sliding column 12 fixedly connected to the surface of the storage box 5, and a pusher 13 fixedly connected to the top of the base 1. When the hydraulic telescopic rod 9 is activated, the output end of the hydraulic telescopic rod 9 extends and retracts toward the connecting platform 10. When the connecting platform 10 moves forward, it causes the movable sleeve 4 at the bottom of the storage box 5 to rotate on the surface of the fixed column 3, so that the entire storage box 5 is in a slanted state, which facilitates the unloading of building materials inside the storage box 5.

[0027] There are two fixed baffles 2, which are symmetrically and evenly distributed around the top center of the base 1. The storage box 5 is located at one end of the two fixed baffles 2 that are close to each other.

[0028] The top of the connecting platform 10 is fixedly connected to the bottom of the storage box 5, and the limiting slide post 12 passes through the slide groove 11.

[0029] The top of the base 1 is fixedly connected to a limiting sleeve 14, and a sliding column 15 is slidably connected inside the limiting sleeve 14. A buffer spring 16 is fixedly connected to the top of the sliding column 15, and a caster wheel 17 is installed at the bottom of the sliding column 15.

[0030] The limiting sleeve 14 is located at the top of the base 1 near the pusher 13.

[0031] The front of the storage box 5 is fixedly connected to a card holder 18, and a baffle 19 is snapped into the inside of the card holder 18. A limit card plate 20 is fixedly connected to the front of the baffle 19.

[0032] The limit plate 20 is attached to the top of the card table 18.

[0033] The implementation principle of a construction trolley for easy unloading in this embodiment is as follows: When unloading the construction trolley, the baffle 19 is first pulled out from the inside of the mounting plate 18. At this time, the material inside the storage box 5 is exposed. Through the storage box 5, the hydraulic telescopic rod 9 is activated. The output end of the hydraulic telescopic rod 9 extends and retracts towards the connecting platform 10. When the connecting platform 10 moves forward, it drives the movable sleeve 4 at the bottom of the storage box 5 to rotate on the surface of the fixed column 3, so that the entire storage box 5 is in a slanted state, which facilitates the unloading of building materials inside the storage box 5. Through the limiting sliding column 12, when the storage box 5 is rotated and slanted, the limiting sliding column 12 slides inside the sliding groove 11 to limit the position of the entire storage box 5.

[0034] When the trolley moves as a whole, the universal wheel 17 is vibrated, and the sliding column 15 presses against the buffer spring 16 to cushion the base 1 at the top of the whole.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
