Description

Technical Field

[0001] This utility model relates to the field of handling device technology, and in particular to a small component handling device for construction sites. Background Technology

[0002] In the construction process, the handling of small components is a crucial link throughout the entire construction cycle. These components include bricks, small embedded steel bars, precast concrete blocks, pipe joints, etc., and are characterized by diverse specifications, small single-transport volume, but extremely high frequency of handling. Their handling efficiency directly affects the progress of construction. Currently, the handling of these small components on construction sites still mainly relies on traditional flatbed carts or simple hand-pushed carts. These handling equipment generally adopts a rigid connection structure, that is, the frame body and handle are fixedly welded as one piece, and the bottom relies only on ordinary rollers for ground movement.

[0003] However, the construction site environment is significantly complex and unique: the ground often has a large number of obstacles due to earthwork operations, material stacking, temporary construction, etc., including scattered piles of gravel, construction ditches of varying depths, protruding steel bars and scaffolding poles, and uneven potholes caused by mechanical compaction. Due to the limitations of the structural design, traditional handling equipment relies entirely on the rolling of rollers against the ground to move. The frame and handles have no adjustable structure. When encountering the above obstacles in the travel path, the rollers cannot cross them directly. The only way to get through is for on-site workers to manually lift the front of the cart or lift the entire cart.

[0004] Based on the above viewpoints, those skilled in the art have proposed a small component handling device for construction sites. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a small construction component handling device. This device constructs a lever structure through a support member, and combines the sliding cooperation between the fixed frame and the handle. When encountering an obstacle, pressing the handle will cause the fixed frame to move closer to the handle, driving the roller to easily cross the construction site ditches or obstacles. There is no need for workers to lift the vehicle, which greatly reduces labor intensity and is suitable for complex construction site environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a small component handling device for construction sites, comprising: The frame is constructed by welding L-shaped steel components and steel plates. The rollers are fitted into the bottom of the placement frame and roll in cooperation with the placement frame. The fixing bracket is welded to the bottom of the front side wall of the frame. A handle is located on the front side of the mounting frame and slides with the mounting frame. A support component is provided on the handle so that the fixing frame and the handle form a lever component.

[0007] Preferably, guide rails are fixedly connected to the outer walls of the rod-shaped portions on both sides of the handle, and the other end of the guide rails is sleeved on the outer side of the rod-shaped portion of the fixing frame.

[0008] Preferably, a sliding rod is fixedly connected to the rear side of the rod-shaped portion of the handle. The sliding rod is slidably engaged with the inner side of the rod-shaped portion of the fixing frame, and a limiting protrusion is provided at the end of the sliding rod to prevent the sliding rod from completely sliding out of the interior of the fixing frame.

[0009] Preferably, each of the guide rails is rotatably connected to a fixing component at its end to lock the relative position of the fixing frame and the handle.

[0010] Preferably, the fixing component includes a turntable, the top of which is fixedly connected to a limiting frame, and the inside of the limiting frame is connected to a fixing member by a spring. Fixing grooves are provided on the top of both the guide rail and the fixing frame, and the bottom of the fixing member passes through the limiting frame and the turntable and extends into the fixing groove.

[0011] Preferably, the support is fixed to the top of the fixing member.

[0012] This utility model has the following beneficial effects: 1. In this utility model, a lever structure is constructed based on the support component. Combined with the sliding cooperation between the fixed frame and the handle, when encountering an obstacle, pressing the handle can cause the fixed frame to move towards the handle, driving the roller to easily cross the construction site ditch or obstacle. There is no need for workers to lift the vehicle, which greatly reduces labor intensity and is suitable for complex construction site environments.

[0013] 2. In this utility model, the handle and the fixed frame are locked by means of a fixing component: during normal handling, the fixing component is inserted into the fixing groove to prevent the handle from sliding relative to each other; at the same time, the fixing component can rotate to drive the support component to be raised or lowered. When raised, it can prevent the support component from touching obstacles and hindering the movement of the trolley, thus improving the flexibility and smoothness of use. Attached Figure Description

[0016] 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.

[0017] Reference Figure 1-4 The present invention provides an embodiment of a small construction component handling device, comprising: a placement frame 1, which is welded from an L-shaped steel component and a steel plate; rollers 2, which are fitted and installed at the bottom of the placement frame 1 and roll in cooperation with the placement frame 1; a fixing frame 3, which is welded to the bottom of the front side wall of the placement frame 1; a handle 6, which is disposed on the front side of the fixing frame 3 and slides in cooperation with the fixing frame 3; and a support member 4, which is disposed on the handle 6 so that the fixing frame 3 and the handle 6 form a lever member.

[0018] This handling device utilizes support member 4 to form a lever structure, which effectively prevents the cart from easily crossing obstacles. It avoids the problem of workers having to carry the cart when it encounters obstacles or ditches, which is quite strenuous when transporting small components. When the cart encounters a ditch or obstacle, simply press handle 6 to lift the end of the fixed frame 3 near the roller 2 off the ground. Since the fixed frame 3 and handle 6 are in a sliding engagement relationship, the fixed frame 3 moves closer to handle 6, allowing the roller 2 to successfully cross the obstacle or ditch. The cart structure designed in this way is simple and reliable, and is suitable for complex environments such as construction sites, greatly improving its practicality.

[0019] In an optional embodiment, guide rails 7 are fixedly connected to the outer walls of the rod-shaped portions on both sides of the handle 6, and the other end of the guide rail 7 is sleeved on the outer side of the rod-shaped portion of the fixing frame 3. The guide rails 7 can limit the sliding of the fixing frame 3 to a certain extent, avoiding structural deformation caused by the fixing frame 3 shifting during sliding.

[0020] In an optional embodiment: a slide rod 8 is fixedly connected to the rear side of the rod-shaped portion of the handle 6. The slide rod 8 is slidably engaged with the inner side of the rod-shaped portion of the fixing frame 3, and a limiting protrusion is provided at the end of the slide rod 8 to prevent the slide rod 8 from completely sliding out of the interior of the fixing frame 3. A fixing component 5 is rotatably connected to the end of each guide rail 7 to lock the relative position of the fixing frame 3 and the handle 6. The fixing component 5 includes a turntable 53, and a limiting frame 52 is fixedly connected to the top of the turntable 53. A fixing member 51 is connected to the inside of the limiting frame 52 by a spring. Fixing grooves 9 are provided at the top of both the guide rail 7 and the fixing frame 3. The bottom of the fixing member 51 passes through the limiting frame 52 and the turntable 53 and extends into the fixing groove 9. During normal handling, the fixing member 51 is inserted into the fixing groove 9 to fix the fixing frame 3 and the slide rod 8 relative to each other. When it is necessary to pry the device, the fixing member 51 is pulled to disengage the fixing member 51 from the fixing groove 9. This locking method can prevent the relative sliding of the handle 6 during the pushing and pulling of the trolley. The support member 4 is fixed to the top of the fixing member 51. When the support 4 is needed, the fixing component 5 can be rotated so that the support 4 touches the ground. When the support 4 is not needed, the handle 6 and the fixing frame 3 can be locked by the fixing component 51. At this time, the support 4 is set upward, which can prevent obstacles from touching the support 4 and causing the trolley to move obstructed.

[0021] Working Principle: This handling device utilizes support component 4 to form a lever structure, effectively preventing the trolley from easily crossing obstacles. This avoids the laborious problem of workers having to manually lift the trolley when transporting small components over obstacles or ditches. When the trolley encounters a ditch or obstacle, simply press handle 6, causing the end of the fixed frame 3 closest to the roller 2 to lift off the ground. Since the fixed frame 3 and handle 6 are in a sliding engagement, the fixed frame 3 moves closer to handle 6, allowing the roller 2 to successfully cross the obstacle or ditch. The trolley designed using this method has a simple and reliable structure and is suitable for complex environments such as construction sites. The improved design greatly enhances its practicality. When there is no need to cross obstacles or ditches, the fixing member 51 is inserted into the fixing groove 9 to fix the fixing frame 3 and the sliding rod 8. When it is necessary to pry the device, the fixing member 51 is pulled to disengage it from the fixing groove 9. This locking method can prevent the handle 6 from sliding relative to the other side during the pushing and pulling of the trolley. When the support member 4 is needed, the fixing component 5 can be rotated to make the support member 4 touch the ground. When the support member 4 is not needed, the fixing member 51 is used to lock the handle 6 and the fixing frame 3. At this time, the support member 4 is set upward, which can prevent obstacles from touching the support member 4 and causing the trolley to move in a blocked manner.

[0022] 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.
