Description

Technical Field

[0001] The present application relates to the technical field of transportation equipment, and in particular to a construction steel material transportation device. Background Art

[0002] As a key equipment supporting the rapid development of the modern construction industry, the importance of construction steel transportation equipment has become increasingly prominent with the increasing number of steel structures such as high-rise buildings, large bridges and stadiums. These complex construction projects not only require high quality steel, but also set strict standards for the transportation efficiency and safety of steel.

[0003] Traditional steel transport vehicles, as the main force in transporting construction steel, are usually composed of core components such as frames, rollers, motors and control systems. The frame, as the main structure that carries the steel, is mostly made of high-strength steel to ensure its sufficient load-bearing capacity and stability. The combination of rollers and motors gives the transport vehicle the ability to move flexibly, while the control system is like the "brain" of the transport vehicle, which achieves precise control of the movement, speed and direction of the transport vehicle through precision components such as operating panels, sensors and controllers.

[0004] However, in actual applications, traditional steel transport vehicles still face many challenges. Especially in terms of loading and fixing steel, although the frame is equipped with loading and fixing devices such as clamps, hooks, and ropes, these devices often cannot provide adequate protection when facing special steel that is prone to corrosion and oxidation. In order to deal with this problem, workers often need to install tarpaulins for shielding, but this process is not only cumbersome and complicated, but also requires close cooperation among multiple staff members, which undoubtedly greatly prolongs the loading time of steel and reduces transportation efficiency, leaving room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide a construction steel material transportation device to solve the problem in the above-mentioned related art that the installation of tarpaulins on transport vehicles is complicated, time-consuming and inefficient.

[0006] The present application provides a construction steel material transportation device adopting the following technical solution:

[0007] A construction steel material transportation device comprises a vehicle body, a plurality of rollers fixedly arranged on the bottom side of the vehicle body and a driving member for controlling the operation of the rollers; a traction handle is hingedly connected to a vertical surface on one side of the vehicle body and a control member for controlling the rotation and adjustment of the traction handle is fixedly arranged; a receiving groove is provided on the side of the traction handle facing the vehicle body and a cover plate for sealing the receiving groove is detachably installed; a tarpaulin is provided on the side of the vehicle body with one side fixedly connected to the inner wall of the receiving groove, a traction member is provided on the side of the vehicle body away from the traction handle, the traction member is used to pull the other side of the tarpaulin to move in a direction away from the traction handle, and the tarpaulin can be covered on the upper part of the vehicle body under the action of the traction member.

[0008] By adopting the above technical solution, when the tarpaulin is not needed for shielding and protection, the tarpaulin is placed in the receiving groove, and the opening of the receiving groove is blocked with a cover plate; when the tarpaulin is needed, the cover plate is opened in advance, and then the installation angle of the traction handle is adjusted, and then the traction member is used to pull the other side of the tarpaulin away from the traction handle, and finally the tarpaulin is covered on the upper part of the vehicle body under the action of the traction member; thereby reducing the difficulty of unfolding the tarpaulin, shortening the corresponding time, and improving the overall efficiency.

[0010] By adopting the above technical solution, when the tarpaulin needs to be covered, the end of the traction rope is fixed to the other side of the tarpaulin in advance, and then the traction motor is started to drive the traction wheel to rotate synchronously, and then the traction rope is rolled up onto the traction wheel, so as to drag the tarpaulin to cover the upper side of the vehicle body.

[0011] Optionally, the control component includes a control motor fixedly mounted on a side of the vehicle body close to the traction handle, and an output shaft of the control motor is coaxially fixedly connected to a rotating shaft of the traction handle.

[0012] By adopting the above technical solution, when the installation angle of the traction handle needs to be adjusted, the motor is controlled to drive the traction handle to rotate, so as to control the traction handle to reciprocate in the direction close to the vehicle body; and when not towing, the traction handle can be rotated to a horizontal state.

[0013] Optionally, a support plate is fixedly provided on the side edge of the traction handle away from the vehicle body, the support plate is perpendicular to the traction handle, and the end of the support plate can abut against the ground when the traction handle is rotated to a horizontal state.

[0014] By adopting the above technical solution, due to the installation arrangement of the support plate on the traction handle, when the steel is loaded into the vehicle body, the traction handle is rotated to a horizontal state. At this time, the combined structure of the traction handle and the support plate can act as a step in this state, which is convenient for loading and unloading of the steel.

[0016] By adopting the above technical solution, due to the combined arrangement of the limiting groove, the accommodating groove and the locking member, when the tarpaulin is covered, the cover plate can be rotated and inserted into the accommodating groove for temporary storage, and then fixed by the locking member; when the tarpaulin is stored inside the accommodating groove, the cover plate is used for sealing, and the locking member is used to fix the cover plate.

[0017] Optionally, support rods are slidably provided in the vertical direction on two opposite vertical side surfaces of the vehicle body, and the vehicle body is provided with an adjusting member for driving the support rod to move downward and an elastic reset member for driving the support rod to reset upward; when the traction handle is in a vertical state, there is a gap between the lower end of the support rod and the ground, and when the traction handle is in other states, the lower end of the support rod moves downward through the action of the adjusting member and abuts against the ground.

[0018] By adopting the above technical solution, due to the combined arrangement of the support rod, the adjusting member and the elastic return member, when the traction handle is in a vertical state, the support rod slides upward under the action of the elastic return member, and there is a gap between the lower end of the support rod and the ground; when the traction handle is in other states (inclined or horizontal state), the elastic force of the elastic return member is overcome by the action of the adjusting member, so that the support rod moves downward until the lower end thereof abuts against the ground.

[0019] Optionally, the elastic reset member includes a baffle symmetrically fixed on the side of the support rod and a compression spring fixed on the lower side of the baffle. A positioning block located below the baffle is fixed on the vehicle body. The positioning block is provided with a positioning through hole for the support rod to pass through and slide. The end of the compression spring away from the baffle is fixedly connected to the upper side of the positioning block.

[0020] By adopting the above technical solution, due to the combined arrangement of the baffle, the compression spring and the positioning block, the up and down sliding of the support rod is first limited by the positioning block, and when the support rod moves downward to abut against the ground, the compression spring is compressed; when the adjustment member stops squeezing the upper part of the support rod, the compression spring resets and drives the support rod to move upward as a whole.

[0021] Optionally, an elastic pad is fixedly provided at the lower end of the support rod.

[0022] By adopting the above technical solution, due to the installation arrangement of the elastic pad, when the lower end of the support rod abuts against the ground, the corresponding support stability is improved.

[0024] By adopting the above technical solution, due to the combined arrangement of the connecting rod, the adjusting rod and the adjusting protrusion, when the support rod is needed to play a supporting role, the traction handle is adjusted to a non-vertical state. During this process, the adjusting rod slides, causing the adjusting protrusion to slide along the guide inclined surface to abut against the upper end surface of the support rod, overcoming the elastic force of the elastic reset member, and causing the support rod to move downward to abut against the ground; under normal conditions, the adjusting rod drives the adjusting protrusion to slide and be misaligned with the upper end portion of the support rod, and the upper end surface of the support rod moves upward under the action of the elastic reset member to abut against the lower side surface of the adjusting rod.

[0025] Optionally, a plurality of hooks are fixedly provided on two opposite sides of the tarpaulin, and a hanging ring for the hooks to be engaged is fixedly provided on the outer side of the adjusting rod.

[0026] By adopting the above technical solution, after the tarpaulin is covered on the vehicle body, due to the combined arrangement of the hooks and the hanging rings, the hooks on both edges of the tarpaulin are hooked into the hanging rings on the adjusting rod, thereby achieving rapid fixation of the tarpaulin and facilitating subsequent rapid disassembly.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] When the tarpaulin is not needed for shielding and protection, the tarpaulin is placed in the receiving groove and the opening of the receiving groove is blocked with a cover plate; when the tarpaulin is needed, the cover plate is opened in advance, and then the installation angle of the traction handle is adjusted, and then the traction member is used to pull the other side of the tarpaulin away from the traction handle, and finally the tarpaulin is covered on the upper part of the vehicle body under the action of the traction member; this reduces the difficulty of unfolding the tarpaulin, shortens the corresponding time, and improves the overall efficiency.

[0041] When the tarpaulin 4 is not used for shielding and protection, the tarpaulin 4 is placed in the receiving groove 21, and the opening of the receiving groove 21 is blocked by the cover plate 12; when the tarpaulin 4 is needed, the cover plate 12 is opened in advance, and then the installation angle of the traction handle 2 is adjusted, and then the traction member 5 is used to pull the other side of the tarpaulin 4 away from the traction handle 2, and finally the tarpaulin 4 is covered on the upper part of the vehicle body 1 under the action of the traction member 5.

[0042] Reference Figure 1 and Figure 2 The traction member 5 includes a traction motor 51 symmetrically fixed on the side of the vehicle body 1 away from the traction handle 2, a traction wheel 52 coaxially fixedly connected to the output shaft of the traction motor 51, and a traction rope 53 with one end fixed on the outer periphery of the traction wheel 52, wherein the other end of the traction rope 53 can be detachably connected (fastened) to the side edge of the tarpaulin 4 away from the traction handle 2;

[0043] The control component 3 includes a control motor 31 fixedly mounted on the side of the vehicle body 1 close to the traction handle 2, and the output shaft of the control motor is coaxially fixedly connected with the rotating shaft of the traction handle 2; when the control motor 31 is running, it drives the traction handle 2 to rotate, and when the traction handle 2 is in a vertical state, one side of the traction handle 2 is in contact with the vertical side of the vehicle body 1, and the staff can control the traction handle 2 to control the movement of the vehicle body 1.

[0044] Reference Figure 2 and Figure 3 A support plate 6 is fixedly provided on the side edge of the traction handle 2 away from the vehicle body 1, wherein the support plate 6 is perpendicular to the traction handle 2. When the traction handle 2 is rotated to a horizontal state, the support plate 6 is in a vertical state, and the lower end of the support plate 6 is in contact with the ground in this state; when steel is loaded into the vehicle body 1, the combined structure of the traction handle 2 and the support plate 6 can act as a step in this state, which is convenient for loading and unloading of steel.

[0045] Reference Figure 3 and Figure 4A limited position sinking groove 22 is provided at the inner edge of the opening of the accommodating groove 21, wherein the side of the cover plate 12 away from the vehicle body 1 is hinged to the inner wall of the limited position sinking groove 22, and the side of the traction handle 2 facing the vehicle body 1 can be rotated and inserted into the other side of the limited position sinking groove 22;

[0048] Reference Figure 5 Two support rods 7 are slidably provided on two opposite vertical sides of the vehicle body 1 in the vertical direction, and a rubber elastic pad 71 is fixedly provided at the lower end of the support rod 7; an adjusting member 8 for driving the support rod 7 to move downward and an elastic reset member 9 for driving the support rod 7 to reset upward are provided on the vehicle body 1;

[0049] When the traction handle 2 is in a vertical state, there is a gap between the lower end of the support rod 7 and the ground; when the traction handle 2 is in other states (inclined or horizontal state), the adjustment member 8 overcomes the elastic force of the elastic reset member 9, so that the support rod 7 moves downward until the lower end contacts the ground.

[0050] Reference Figure 6 The adjusting member 8 includes a connecting rod 81 hinged to the traction handle 2 at one end and an adjusting rod 82 slidably arranged on the vertical side of the vehicle body 1 in the horizontal direction. The adjusting rod 82 can slide back and forth along its own length direction, and the adjusting rod 82 is located above the support rod 7. The end of the adjusting rod 82 close to the traction handle 2 is hinged to the other end of the connecting rod 81. Two adjusting protrusions 821 corresponding to the support rod 7 are fixed on the side of the adjusting rod 82 facing the support rod 7, wherein a guiding inclined surface 8211 is arranged on the lower edge of the adjusting protrusion 821.

[0051] When the support rod 7 is needed to play a supporting role, the traction handle 2 is adjusted to a non-vertical state. During this process, the adjusting rod 82 slides, causing the adjusting protrusion 821 to slide along the guide inclined surface 8211 to abut against the upper end surface of the support rod 7, thereby overcoming the elastic force of the elastic reset member 9 and causing the support rod 7 to move downward to abut against the ground; under normal circumstances, the adjusting rod 82 drives the adjusting protrusion 821 to slide and be misaligned with the upper end portion of the support rod 7.

The end of the compression spring 92 away from the baffle 91 is fixedly connected to the upper side of the positioning block 14.

[0053] Reference Figure 6 and Figure 7 A plurality of hooks 41 are fixedly arranged on the two opposite sides of the tarpaulin 4, and a plurality of hanging rings 822 for the hooks 41 to be inserted into are fixedly arranged on the outer side of the adjusting rod 82 along its length direction; after the tarpaulin 4 is covered on the vehicle body 1, the hooks 41 on the two edges of the tarpaulin 4 are inserted into the hanging rings 822 on the adjusting rod 82, so as to further quickly fix the tarpaulin 4.

[0054] The implementation principle of the embodiment of the present application is:

[0055] When steel is loaded into the vehicle body 1, the traction handle 2 is adjusted to a horizontal state so that the lower end of the support plate 6 abuts against the ground. In this state, the support rod 7 is synchronously moved downward to a state of abutting against the ground under the pressure of the adjustment protrusion 821; and the combined structure of the traction handle 2 and the support plate 6 can act as a step in this state, which is convenient for loading and unloading steel;

[0056] When covering the tarpaulin 4, the traction handle 2 is adjusted to a state of being tilted upward by 45 degrees. In this state, the support rod 7 is synchronously moved downward to a state of contact with the ground under the pressure of the adjustment protrusion 821; then the cover plate 12 is opened and rotated to be fixed in the accommodating sink 61, and then the traction member 5 is used to pull the other side of the tarpaulin 4 away from the traction handle 2. Finally, the tarpaulin 4 is covered on the upper part of the vehicle body 1 under the action of the traction member 5, and the hooks 41 on the two edges of the tarpaulin 4 are clamped into the hanging rings 822 on the adjustment rod 82;

[0057] When the transport device is moved for transportation, the traction handle 2 is adjusted to a vertical state, and the traction handle 2 drives the adjustment rod 82 to slide through the connecting rod 81 until the adjustment protrusion 821 slides and is misaligned with the upper end of the support rod 7. The upper end surface of the support rod 7 moves upward under the action of the elastic reset member 9 to abut against the lower side surface of the adjustment rod 82, and there is a gap between the lower end of the support rod 7 and the ground; in this state, the traction member 5 also indirectly pulls the traction handle 2 through the tarpaulin 4, reducing the possibility of the traction handle 2 being loosened in this state.
