Description

Technical Field

[0001] The utility model relates to the technical field of construction material transport vehicles, in particular to a material transport device for civil construction. Background Art

[0002] Civil construction refers to the construction of civil engineering projects, covering the construction of buildings, structures, and engineering objects within the facilities and places within the scope of houses, roads, railways, airports, bridges, water conservancy, ports, tunnels, water supply and drainage, protection, etc., on the ground, underground, on land, in the water, and underwater. During the civil construction process, some sections of the road are too narrow and muddy to be convenient for motor vehicles to pass, so it is often necessary to use carts to transport cement, sand, stone and other materials over short distances.

[0003] The invention patent application with application publication number CN106516609A discloses a material transport vehicle for construction, which uses a hook rod to hook a hanging groove to achieve the balance of the loading bucket on the supporting bottom plate, ensuring that the loading bucket is not easy to tip over during transportation, and limits the maximum flipping range of the loading bucket by setting a sleeve and a telescopic rod to prevent the loading bucket from over-flipping and interacting with the ground. However, when unloading the material transport vehicle for construction, the worker still needs to lift one side of the loading bucket to pour out the material in the loading bucket, which is very laborious when the bucket is full of materials. Utility Model Content

[0004] The utility model aims to provide a material handling device for civil construction in view of the defects of the prior art, which utilizes the lever principle to reduce the force required to lift one side of the bucket when unloading.

[0005] In order to solve the above technical problems, the utility model provides a material handling device for civil construction, including a bracket and wheels arranged at the four corners of the bracket, a bucket is arranged on the bracket, and the bracket includes a first bracket and a second bracket, the bottom of the bucket is fixedly connected to the first bracket, the bottom of the bucket is fitted with the second bracket, the second bracket is rotatably connected to the first bracket, a push rod is arranged on the side of the second bracket away from the first bracket, the wheel axle of the wheel on the second bracket is a lever fulcrum, the horizontal distance between the end of the push rod away from the second bracket and the lever fulcrum is a, and the horizontal distance between the rotational connection between the second bracket and the first bracket and the lever fulcrum is b, wherein a>b.

[0006] The second bracket and the first bracket of the utility model are rotatably connected. When the push rod is pressed downward, the push rod will drive the second bracket to tilt up, causing the first bracket to rotate, thereby tipping the bucket fixed on the first bracket forward to achieve unloading. The second bracket and the push rod are fixedly connected. The second bracket and the push rod can be regarded as a lever. The axle of the wheel at the bottom of the second bracket is the fulcrum of the lever. Since a>b, the force required to tilt the second bracket can be reduced, so that workers can easily pour out the materials in the bucket.

[0007] Furthermore, a pin seat is provided on the second bracket, a fixing block is provided on the truck bed, a pin hole is provided on the pin seat, and a fixing hole corresponding to the pin hole is provided on the fixing block, and the truck bed can be fixed by inserting a pin into the pin hole and the fixing hole.

[0008] The utility model can fix the bucket and the second bracket by arranging the fixing block and the pin seat, thereby preventing the bucket from rotating during transportation.

[0009] Furthermore, two pin seats are provided, and the fixing block is arranged between the two pin seats.

[0010] The utility model reduces the force on the pin seats by arranging two pin seats.

[0011] Furthermore, the pin seat is arranged on a side of the second bracket away from the first bracket, and the fixing block is arranged on a side of the bucket close to the push rod.

[0012] The pin seat of the utility model is arranged on the side of the second bracket away from the first bracket. Compared with the pin seats arranged on both sides of the truck bucket, the force required for the pin seat to fix the truck bucket is smaller.

[0013] Furthermore, a ring is provided at one end of the latch pin, and the ring is connected to the push rod via a connecting rope.

[0014] The utility model provides a ring on the latch and connects the ring with the push rod through a connecting rope, which makes it easy for workers to pull out the latch and prevents the latch from being lost.

[0015] Furthermore, a bottom plate is fixedly arranged on the first bracket, the bucket is fixedly arranged on the bottom plate, a buffer block is arranged on the second bracket, and a thickness of the buffer block is greater than or equal to a thickness of the bottom plate.

[0016] The utility model can prevent the bucket from directly hitting the second bracket when rotating by arranging the buffer pad, thereby reducing the influence on the connection between the second bracket and the first bracket.

[0017] Furthermore, the push rod includes a connecting rod and a handle, one end of the connecting rod is fixedly connected to the second bracket, and the other end of the connecting rod is fixedly connected to one end of the handle, the connecting rod is arranged at the end of the second bracket away from the first bracket, the angle between the connecting rod and the second bracket is an obtuse angle, and the handle is arranged parallel to the bracket.

[0018] The angle between the connecting rod and the second bracket of the utility model is an obtuse angle, which can increase the distance between the handle and the lever fulcrum and reduce the force required for unloading.

[0019] Further, the first bracket includes a first cross bar and a plurality of first longitudinal bars, one end of the first longitudinal bar is fixedly connected to the first cross bar, and the first longitudinal bar is arranged perpendicular to the first cross bar, the second bracket includes a second cross bar and a plurality of second longitudinal bars, one end of the second longitudinal bar is fixedly connected to the second cross bar, and the second longitudinal bar is arranged perpendicular to the second cross bar, the first cross bar and the second cross bar are arranged in parallel, and the other end of the first longitudinal bar is rotatably connected to the other end of the second longitudinal bar via a rotating shaft.

[0020] The bracket of the utility model can be formed by only three rods, and has a simple structure and low cost.

[0021] Furthermore, a mounting seat is fixedly arranged at the bottom of the second bracket and the first bracket, and the wheel is rotatably connected to the mounting seat via a wheel axle.

[0022] Furthermore, a side of the bucket away from the push rod forms an acute angle with a horizontal plane.

[0023] The side of the bucket of the utility model away from the push rod forms an acute angle with the horizontal plane, so that the material loaded in the bucket can be unloaded after the bucket is rotated at a small angle.

[0024] The beneficial effects of the utility model are as follows: the second bracket and the first bracket of the utility model are rotatably connected. When the push rod is pressed downward, the push rod will drive the second bracket to tilt up, causing the first bracket to rotate, thereby tipping the truck bucket fixed on the first bracket forward to achieve unloading. The second bracket and the push rod are fixedly connected. The second bracket and the push rod can be regarded as a lever. The axle of the wheel at the bottom of the second bracket is the fulcrum of the lever. Since a>b, the force required to tilt the second bracket can be reduced, so that workers can easily pour out the materials in the truck bucket. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] like Figure 1 As shown, this embodiment provides a material handling device for civil construction, including a bracket and a bucket 5 arranged on the bracket.

[0033] like Figure 2 As shown, the bracket includes a first bracket 1 and a second bracket 2, the first bracket 1 includes a first cross bar and two first longitudinal bars, one ends of the two first longitudinal bars are respectively fixedly connected to the two ends of the first cross bar by welding, and the first longitudinal bar is arranged perpendicular to the first cross bar, the second bracket 2 includes a second cross bar and two second longitudinal bars, one ends of the two second longitudinal bars are respectively fixedly connected to the two ends of the second cross bar by welding, the second longitudinal bar is arranged perpendicular to the second cross bar, the first cross bar and the second cross bar are arranged in parallel, and the other end of the first longitudinal bar is rotatably connected to the other end of the second longitudinal bar through a rotating shaft.

[0034] The first bracket 1 is provided with a bottom plate 4, the bottom of which is welded to the first cross bar and the two first longitudinal bars, the bucket 5 is fixedly mounted on the bottom plate 4 by bolts or welding, and the two second longitudinal bars of the second bracket 2 are provided with a buffer pad 6, which can be made of rubber material, and the thickness of the buffer pad 6 is equal to the thickness of the bottom plate 4. Two pin seats 9 are welded to the middle of the second cross bar of the second bracket 2, and the two pin seats 9 are coaxially provided with a plug 11 hole, and push rods are welded to both ends of the second cross bar, and the push rods include a connecting rod 7 and a handle 8, one end of the connecting rod 7 is welded to the second cross bar, and the other end of the connecting rod 7 is threadedly connected to one end of the handle 8, and the angle between the connecting rod 7 and the second longitudinal bar is an obtuse angle, and the handle 8 is arranged parallel to the second bracket 2.

[0035] The bottoms of both ends of the first crossbar and the second crossbar are welded with mounting seats, on which wheels 3 are rotatably arranged through axles. It can be understood that the push rod and the second bracket 2 can be regarded as levers, and the axles of the wheels 3 can be regarded as the fulcrums of the levers. By pressing down the handle 8, the two second longitudinal bars of the second bracket 2 can be tilted up, as shown in FIG. Figure 5 In order to reduce the force required to push down the handle 8, the horizontal distance between the end of the push rod away from the second bracket 2 and the lever fulcrum is a, and the horizontal distance between the second longitudinal rod and the first longitudinal rod rotation connection and the lever fulcrum is b, a>b.

[0036] like Figure 3 As shown, the surface of the side of the bucket 5 away from the push rod is set as an inclined plane, which forms an acute angle with the horizontal plane. A fixing block 10 is welded on the side of the bucket 5 close to the push rod. The fixing block 10 has a fixing hole corresponding to the hole of the latch 11.

[0037] The method of using the material handling device for civil construction is as follows: after the materials in the bucket 5 are carried to the designated position, the latch 11 is pulled out from the pin seat 9, at which time the bucket 5 and the second bracket 2 are no longer locked, and the handle 8 on the connecting rod 7 is pressed down. The axle of the wheel 3 at the bottom of the second bracket 2 is the lever fulcrum. During the process of the connecting rod 7 being pressed down, the side of the second bracket 2 that is rotatably connected to the first bracket 1 is lifted, thereby lifting the connection between the first bracket 1 and the second bracket 2, so that the bucket 5 is tilted. Figure 5 As shown, after the bucket 5 is tilted, the material in the bucket 5 can be poured out. After all the materials are poured out, the connecting rod 7 is lifted, the bucket 5 returns to the horizontal position, the fixing block 10 is inserted between the two pin seats 9, and the pin 11 is inserted back into the pin seat 9.
