Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, and in particular to a construction engineering transport cart. Background Technology

[0002] In the construction process, transport carts are indispensable tools used to move various building materials, such as sand, gravel, and bricks.

[0003] Regarding transport trolleys, a search reveals, for example, a construction transport trolley with patent publication number CN222698493U, which includes a bucket, a chassis, a chassis mounted on the lower surface of the bucket, a housing, a shell fixedly mounted on the center of the lower surface of the front end of the chassis, and grooves on the front and rear walls of the shell, a slider, a housing, and shock-absorbing springs symmetrically arranged about the center of the bucket, and a drive shaft passing through the two sliders. This construction transport trolley facilitates shock absorption during equipment movement via the shock-absorbing springs inside the shell, preventing materials from scattering due to excessive speed on bumpy roads. A cylinder drives a push plate to push out any unloaded material from the bucket. During unloading, a hydraulic cylinder lifts the bucket upwards, and after unloading, the hydraulic cylinder presses it down, retracting it into the groove. This ensures the equipment's working efficiency and reduces the user's workload.

[0004] Based on the above search and the findings of existing technologies, existing transport trolleys similar to those disclosed above generally have an inclined bucket design at the front end to facilitate tilting and unloading. However, compared to rectangular buckets, this design has a smaller cargo capacity, requiring more reciprocating transport of the same amount of goods. Therefore, a construction engineering transport trolley is proposed to address these issues. Utility Model Content

[0005] The purpose of this application is to provide a construction engineering transport trolley to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a construction engineering transport cart, comprising a cargo bed with wheels mounted on both sides, and a handle mounted on one side of the cargo bed:

[0007] The side of the truck bed away from the handle is an inclined opening, and a main baffle is rotatably installed at the top of the inclined opening. The rotation range of the main baffle is the angle between the inclined opening and the vertical direction. Side baffles are fixed on both sides of the main baffle near the moving wheel. The side baffles are slidably fitted to the outer wall of the truck bed.

[0008] A movable base plate is horizontally slidably installed at the bottom of the truck bed. A boss is provided at the end of the movable base plate near the handle. A compression spring is fixed between the boss and the end of the truck bed near the handle. The end of the movable base plate away from the boss is in contact with the main baffle.

[0009] As a further supplement to this solution, a guide rod is horizontally fixed at the bottom of the side of the truck bed near the handle, and the guide rod slides through the boss.

[0010] As a further supplement to this solution, a connecting arm is fixed to the side end of the side baffle, and a limiting sleeve is fixed to the side end of the truck bed. The end of the connecting arm away from the side baffle slides through the limiting sleeve and is fixed with a limiting block.

[0011] As a further supplement to this scheme, the edges of the inclined opening away from the side baffle and the movable bottom plate are all chamfered.

[0012] As a further supplement to this solution, a hydraulic cylinder is vertically installed on the outer wall of the truck bed near the handle.

[0013] As a further supplement to this solution, a roller is horizontally rotatably mounted on the end of the movable base plate near the main baffle, and the roller contacts the main baffle.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, by setting up a main baffle, side baffles and a movable bottom plate, when transporting materials, the main baffle and side baffles form a rectangular trough. Compared with the conventional inclined bucket trough, this rectangular trough can hold more goods. When unloading, the bucket is tilted towards the side of its inclined opening. Then, the main baffle rotates due to its contact with the ground, and the movable bottom plate slides towards the handle side under the squeezing action of the main baffle until the entire trolley is in a similar unloading state to the conventional inclined bucket trolley. Under the premise of ensuring smooth unloading, the single loading capacity is increased and the number of transport round trips is reduced, thereby improving transportation efficiency.

[0016] 2. In this utility model, a hydraulic cylinder is vertically installed on the outer wall of the truck bed near the handle. During unloading, the hydraulic cylinder lifts the truck bed upward, causing it to tilt towards the open side, thus achieving automatic unloading and reducing the workload of the workers. A roller is horizontally installed at the end of the movable base plate near the main baffle. The roller contacts the main baffle, and the roller reduces the friction between the main baffle and the movable base plate, allowing the movable base plate to be smoothly pushed by the main baffle.

[0022] 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.

[0023] Example: Reference Figure 1-3 The construction engineering transport trolley shown includes a cargo box 1 with movable wheels 2 installed on both sides, and a handle 3 installed on one side of the cargo box 1.

[0024] The side of the truck bed 1 away from the handle 3 is an inclined opening, and a main baffle 4 is rotatably installed at the top of the inclined opening. The rotation range of the main baffle 4 is the angle between the inclined opening and the vertical direction. In order to stably limit the rotation angle of the main baffle 4, a connecting arm 8 is fixed to the side end of the side baffle 5, and a limiting sleeve 7 is fixed to the side end of the truck bed 1. The end of the connecting arm 8 away from the side baffle 5 slides through the limiting sleeve 7 and is fixed with a limiting block 9.

[0025] Side baffles 5 are fixed to both ends of the main baffle 4 near the moving wheel 2. The side baffles 5 are slidably fitted to the outer wall of the truck bed 1. A movable base plate 6 is horizontally slidably installed at the bottom of the truck bed 1. A boss 12 is provided at the end of the movable base plate 6 near the handle 3. A compression spring 10 is fixed between the boss 12 and the end of the truck bed 1 near the handle 3. A guide rod 11 is horizontally fixed at the bottom end of the side of the truck bed 1 near the handle 3. The guide rod 11 slides through the boss 12. The end of the movable base plate 6 away from the boss 12 is fitted to the main baffle 4.

[0026] Based on the above structural arrangement, during normal material transportation, the main baffle 4 and the side baffle 5, under their own weight, are positioned as follows: Figure 1 and Figure 2 In this state, the main baffle 4, side baffle 5, movable bottom plate 6, and bucket 1 form a rectangular trough. Compared to a conventional tilting bucket trough, this rectangular trough can hold more cargo. During unloading, the bucket 1 is tilted towards its tilted open side. The main baffle 4 then rotates due to contact with the ground, and the movable bottom plate 6 slides towards the handle 3 under the pressure of the main baffle 4, until the entire cart is in the like... Figure 3 As shown in the diagram, its unloading state is similar to that of a conventional tilting bucket trolley, and the unloading effect of both is the same.

[0027] As can be seen from the above, the trolley in this solution increases the single loading capacity and reduces the number of transport round trips while ensuring smooth unloading, thereby improving transportation efficiency.

[0028] Considering that material accumulation on the inclined opening side can easily make it difficult for the main baffle 4 to rotate toward the inclined opening, the edges of the inclined opening away from the side baffle 5 and the movable bottom plate 6 are all set with chamfers 14. The chamfers 14 make it difficult for material to accumulate on the inclined opening side, so that the main baffle 4 can rotate smoothly toward the inclined opening.

[0029] A hydraulic cylinder 13 is vertically installed on the outer wall of the truck bed 1 near the handle 3. The hydraulic cylinder 13 can be a conventional model in the existing technology and is electrically connected to an external controller and power supply using conventional technical means (the external controller and power supply are not shown in the figure). When unloading, the hydraulic cylinder 13 is used to lift the truck bed 1 upward, so that the truck bed 1 tilts towards its tilting open side, thereby realizing automatic unloading and reducing the workload of the workers.

[0030] In order to reduce the friction between the main baffle 4 and the movable base plate 6, a roller is horizontally rotatably installed at the end of the movable base plate 6 near the main baffle 4, and the roller contacts the main baffle 4.

[0031] The working principle of this utility model is as follows: When transporting materials, the main baffle 4 and the side baffle 5 are in a state of equilibrium under their own weight. Figure 1 and Figure 2In this state, the main baffle 4, side baffle 5, movable bottom plate 6 and the bucket 1 form a rectangular groove. Compared with the conventional inclined bucket hopper, this rectangular groove can hold more goods.

[0032] During unloading, the hydraulic cylinder 13 lifts the bucket 1 upwards, causing it to tilt towards its open side. The main baffle 4 then rotates due to contact with the ground, and the movable base plate 6 slides towards the handle 3 under the pressure of the main baffle 4, until the entire cart is in a tilted position. Figure 3 The status shown indicates that automatic unloading has been completed.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
