Description

Technical Field

[0001] The invention belongs to the technical field of equipment transportation, and in particular to an auxiliary device and a construction method for on-site steel bar transportation. Background Art

[0002] In the construction of the spillway and main body of the power station, reinforced concrete is the most common on-site construction. When the steel bar transport vehicles purchased are not enough to meet the construction strength, the transport equipment such as truck cranes and dump trucks are generally used to place the steel bars in the truck bed for direct transportation. Direct transportation in dump trucks is not only unsafe, but also requires a small amount of steel bars.

[0003] In the process of transporting steel bars in hydropower stations, there is not only a certain distance for the steel bars to be transported from the warehouse to the construction site, but also the steel bars are transported in batches. It is impossible to use manpower to carry out large-scale transportation during the on-site transportation process. Generally, steel bar transport vehicles are used for transportation. However, for projects with insufficient equipment and funds, the number of steel bar transport vehicles may be difficult to meet the project progress requirements, resulting in the construction problem of slow steel bar transportation, which ultimately affects the project progress. Summary of the invention

Both ends of the support beam are also connected to baffles, which are on the same side as the long side of the dump truck bucket. The baffles are perpendicular to the support beam, and the unfixed end of the baffle extends away from the top of the dump truck bucket.

[0008] Furthermore, it also includes a second diagonal brace, one end of which is connected to the top of the dump truck bucket, the second diagonal brace is located on the long side of the dump truck bucket, and the other end of the second diagonal brace is connected to the support column.

[0009] Furthermore, the joists and the support columns are both made of angle steel, and the joists and the support columns are both connected by full-contact surface welding.

[0010] Furthermore, vertical pipes are welded to the four corners of the dump truck bucket, the support column is sleeved in the vertical pipe, a locking hole is provided on the vertical pipe, a locking bolt is threadedly connected to the locking hole, and the locking bolt is used to position the support column.

[0011] Furthermore, the baffle is a U-shaped plate, the bottom of the U-shaped plate is welded to the support beam, the two U-shaped plates close to the dump truck head constitute the front end U-shaped plate, and the two U-shaped plates away from the dump truck head constitute the rear end U-shaped plate, and the front end U-shaped plate and the rear end U-shaped plate are connected by a retractable bucket, and the retractable bucket is a top opening structure, and the long side of the retractable bucket can be extended or shortened.

[0012] Furthermore, the retractable truck bucket includes a first placement groove and a second placement groove, the top end faces and one end faces of the first placement groove and the second placement groove are both open structures, the first placement groove is slidably connected in the inner cavity of the front end U-shaped plate, and the second placement groove is slidably connected in the inner cavity of the rear end U-shaped plate, one end face of the first placement groove and one end face of the second placement groove are butt-jointed, and the first placement groove is sleeved on the outer wall of the second placement groove.

[0013] Furthermore, a sliding groove is provided on the bottom end surface of the first placement groove and the bottom end surface of the second placement groove, and the sliding groove is used to penetrate a side plate of the U-shaped plate.

[0014] Furthermore, a plurality of locking holes are provided at intervals on the side walls of the first placement groove and the side walls of the second placement groove, and the plurality of locking holes are provided along the long sides of the first placement groove and the second placement groove. Positioning holes are provided on the plate surfaces of the front end U-shaped plate and the rear end U-shaped plate, and the center of the positioning hole and the center of the locking hole are on the same straight line.

[0015] The present invention also provides a construction method of an auxiliary device for on-site steel bar transportation, comprising the following steps:

[0017] The other ends of the four supporting columns are detachably connected to the four corners of the dump truck bucket, the steel bars are laid on two adjacent supporting beams, and the baffles limit the lateral displacement of the steel bars.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] The present invention provides an auxiliary device for transporting steel bars in a field. The supporting column is detachably connected to the dump truck bucket, and the joist is connected to the supporting column. The joist and the supporting column are used as the overall force-bearing body of the auxiliary device. The baffles welded at both ends of the joist can limit the lateral displacement of the steel bars, thereby forming a platform for placing the steel bars on the top of the dump truck, so that the steel bars can be placed flat on the dump truck, so that the dump truck can be used as a tool for transporting steel bars. The dump truck is used to modify the equipment and replace the steel bar transport vehicle. While the steel bar transport can be completed, the cost is reduced; not only the problem of insufficient steel bar transport vehicles is solved, but also the safety problem of construction personnel directly using the dump truck for transportation due to insufficient steel bar transport vehicles is reduced. If the dump truck is directly used for transportation, it is not only unsafe but also the number of transported steel bars is limited. The height of the baffle of the present invention can increase the storage quantity of steel bars. Moreover, the cost of the dump truck in the present invention is low, the supporting column, the joist and the baffle structure are simple, the required materials are single, the production is convenient and fast, the operability and practicality are strong, the efficiency of steel bar transportation construction in the field is improved, the equipment utilization is improved, the equipment investment cost is reduced, and the economic benefits of the project department construction are improved.

[0020] Furthermore, the provision of the first diagonal brace can increase the stability of the supporting columns and the supporting beams, improve the efficiency of steel bar transportation on the construction site, and reduce the equipment purchase cost of the project department.

[0021] Furthermore, the provision of the second diagonal brace can further enhance the supporting force of the support column, ensuring that the support column can transport more steel bars and improving the safety of transportation.

[0022] Furthermore, the vertical pipes and support columns at the four corners of the dump truck bucket are detachably connected, which can ensure the normal use of the dump truck. When transporting steel bars, the support columns and the dump truck bucket are connected, which is convenient and quick.

[0023] Furthermore, the setting of the retractable truck bed further ensures the safety of steel bar transportation, and the retractable truck bed can be suitable for placing more types of steel bars.

[0024] Furthermore, the docking and interlocking of the first placement groove and the second placement groove can freely adjust the interlocking length of the first placement groove and the second placement groove, so as to meet the requirements of steel bars of different lengths, which not only meets the requirements of safe production, but also can meet the transportation of more types of steel bars, thereby improving the construction efficiency of on-site steel bar transportation.

[0025] Furthermore, the locking holes on the first placement groove and the second placement groove can cooperate with the positioning holes on the U-shaped plate. When they are coaxial, the coaxial locking holes and positioning holes can be locked by external screws or other components, which can stabilize the length of the retractable truck bed and improve the usability of the dump truck. There is no need to configure an overly valuable steel bar transport vehicle, saving construction costs. BRIEF DESCRIPTION OF THE DRAWINGS
