Description
Technical Field
[0001] The present invention relates to the technical field of transport equipment, and in particular to a transport vehicle. Background Art
[0002] A transport truck is a device used to transport and transfer large items. It is mostly used to transport cement sandbags at construction sites, deliver large barrels of water to homes in small areas, or transport heavier items.
[0003] When using a transport truck to transport items that are too large or too high, the transport process will be more difficult and the items will be inconvenient to fix. To address this problem, the patent document with announcement number CN210653151U proposes a frame-type transport truck adjustment device, which uses an elastic rope with a hook tied to the frame. After placing the items, the elastic rope is wrapped around the items and the transport truck frame to fix the items on the transport truck.
[0004] However, the use of a single elastic rope for manually bundling items in the prior art still has the following problems: first, in the above-mentioned prior art, when the items need to be fixed on the transport cart, the staff is required to slowly put the transport cart and the items in place, and then hold the two ends of the elastic rope to tighten and bundle the elastic rope. However, if the elastic rope is tightened with a large force at this time, the force exerted by the elastic rope on the frame of the transport cart is also large. Since the two wheels and the frame of the transport cart are in contact with the ground at the same time when the transport cart is placed, there is a risk of the wheels rotating when the frame is subjected to a large force. When a smaller force is used to pull the elastic rope, the elastic rope still has a large amount of expansion and contraction after the bundling is completed. At this time, the fixation of the items on the transport cart is not firm, and there is a risk of the items shaking or even falling off during the movement of the transport cart. Summary of the invention
[0005] The present invention aims at the problems in the prior art and provides a transport cart which is convenient for workers to fix the transported articles. The present invention solves the problem in the prior art that when fixing the articles on the transport cart, the workers need to slowly put the transport cart and the articles in place, and then hold the two ends of the elastic rope to tighten and tie the elastic rope with great force, which may cause the transport cart to rotate; or the elastic rope is pulled and tied with less force, which may cause the articles on the transport cart to be not firmly fixed.
[0006] The technical solution adopted by the present invention is as follows:
[0007] A transport vehicle comprises an L-shaped frame, wherein the L-shaped frame comprises a vertical portion at an upper end and a horizontal portion at a lower end, wherein two wheels are symmetrically arranged on the frame, and further comprises an elastic band and a fastening mechanism, wherein one end of the elastic band is fixedly arranged on the frame, and the other end of the elastic band is connected to the fastening mechanism, and the fastening mechanism comprises a support plate fixedly arranged on the frame, a collecting tray is fixedly arranged on the support plate, a rotating shaft is arranged on the collecting tray, one end of the rotating shaft is located between the collecting tray and the frame and is connected to the other end of the elastic band, and the other end of the rotating shaft is connected to a handle, and at least one fixing member is arranged on the collecting tray, and the handle can be snapped into the fixing member. By setting up the elastic band and fastening mechanism, after placing the transported items on the transport cart, the elastic band is placed on the outside of the items, and then the staff turns the handle, and the excess part of the elastic band will be collected on the rotating shaft. At this time, the staff only needs to determine whether the elastic force of the elastic band is sufficient to fix the items on the transport cart. When the item is fixed, the handle is clamped in the nearest fixing part to complete the fixation. There is no need to manually tighten the elastic band, which avoids the shaking of the vehicle body caused by manually tightening the elastic band. At the same time, it also avoids the situation where the elastic band is not firmly fixed to the items on the transport cart when a small force is used to pull the elastic band deliberately to ensure the stability of the vehicle body, thereby avoiding the risk of the items shaking or even falling off during the movement of the transport cart.
[0008] Preferably, two support plates are arranged horizontally in the vertical direction, and the upper support plate is connected to a guide plate, which is arranged in an arc shape and is used to abut against the elastic band to make the elastic band flip. Through the arranged guide plate, the elastic band can be rotated 90° during the process of collecting the elastic band, so as to facilitate the collection on the rotating shaft.
[0009] Preferably, three fixing members are provided, and the three fixing members are evenly distributed on the collecting plate. With multiple fixing members, when the staff determines that the fixing force of the items on the transport vehicle is sufficient, the handle is clamped in the nearest fixing member to complete the fixing, thereby avoiding the need to adjust the elasticity of the elastic band too high or too low according to the position of the fixing member when there is only one fixing member.
[0010] Preferably, the transport vehicle further comprises a telescopic frame, which is arranged in the frame and can move in the vertical direction. By providing the telescopic frame, the adaptability range of the transport vehicle to the height of the transported object can be increased, and the space occupied by the transport vehicle can be reduced by retracting the telescopic frame when storing the transport vehicle.
[0011] Preferably, an adjustment rod is provided in the telescopic frame, the lower end of the adjustment rod is hinged to at least one end of a connecting rod, the other end of each connecting rod is connected to a clamping piece, and at least two accommodating grooves are provided on the frame, and the clamping piece can be inserted into the accommodating groove. Through the provided connecting rod and the adjustment rod, when it is necessary to pull out or retract the telescopic frame, the adjustment clamping rod is pulled upward to drive the connecting rod to retract, and the clamping piece is separated in the corresponding accommodating groove, and the telescopic frame can be extended and retracted. When it is extended to a preset position, the adjustment rod is pushed downward, and the clamping piece driven by the connecting rod is inserted into the corresponding accommodating groove, thereby completing the fixing of the telescopic frame.
[0012] Preferably, the lower end of the adjusting pull rod is hinged with two connecting rods, the two connecting rods are symmetrically arranged, and two accommodating grooves are provided on each side end surface of the frame. By providing the two connecting rods, the telescopic frame can be fixed more firmly on the frame.
[0013] Preferably, at least one brake mechanism is also included, each brake mechanism includes a handle fixedly mounted on the telescopic frame, a brake grip is arranged below the handle, the brake mechanism also includes a mounting plate fixedly mounted on the frame, a transmission member is hinged on the mounting plate, the middle part of the transmission member is hinged on the mounting plate, one end of the transmission member is connected to the brake grip through a brake line, a brake plate is also hinged on the mounting plate, a brake block is fixed on the brake plate, the other end of the transmission member can abut against the brake plate, and the brake block can abut against the wheel. When the transport vehicle needs to be decelerated by the brake mechanism, the staff pulls the brake grip to lift one end of the transmission member, and the other end of the transmission member moves downward to abut against the brake plate. The brake plate moves downward and drives the brake block on the brake plate to move downward. The brake block abuts and rubs against the tire below to complete the deceleration of the transport vehicle.
[0014] Preferably, the brake mechanism further comprises an elastic member, one end of which is fixedly arranged on a frame below the transmission member, and the other end of the elastic member is fixedly connected to one end of the transmission member, and the elastic member is always in a stretched state. Through the provision of the elastic member, when the staff releases the brake handle after completing the braking, the elastic member which is always in a stretched state pulls one end of the transmission member downward, and at this time the other end of the transmission member moves upward, so that the brake block is separated from the tire, and there is no need to manually separate the brake block from the tire, thereby reducing the time of releasing the brake state.
[0015] It can be seen from the above technical scheme that the advantages of the present invention are: through the elastic band and the fastening mechanism, after placing the transported items on the transport vehicle, the elastic band is placed on the outside of the items, and then the staff turns the handle, and the excess part of the elastic band will be collected on the rotating shaft. At this time, the staff only needs to check whether the elastic force of the elastic band meets the fixation of the items on the transport vehicle. When the fixation of the items is satisfied, the handle is clamped in the nearest fixing piece to complete the fixation. There is no need to manually tighten the elastic band, avoiding the shaking of the vehicle body caused by manually tightening the elastic band. At the same time, it also avoids deliberately ensuring the stability of the vehicle body and pulling the elastic band with a small force. The elastic band is not firmly fixed to the items on the transport vehicle, thereby avoiding the risk of shaking or even falling of the items during the movement of the transport vehicle. Through the guide plate, the elastic band can be rotated 90° during the collection of the elastic band to facilitate the collection on the rotating shaft. Through the multiple fixings, when the staff determines that the fixing force of the items on the transport vehicle is satisfied, the handle is clamped in the nearest fixing piece to complete the fixation, avoiding the single fixing piece is required to adjust the elasticity of the elastic band too high or too low according to the position of the fixing piece. The telescopic frame can increase the adaptability of the transporter to the height of the transported object, and the space occupied by the transporter can be reduced by retracting the telescopic frame when storing the transporter. Through the connecting rod and the adjusting rod, when it is necessary to pull out or retract the telescopic frame, the adjusting rod is pulled upward to drive the connecting rod to retract. At this time, the clamping part is separated in the corresponding accommodating groove, and the telescopic frame can be extended and retracted. When it is extended to the preset position, the adjusting rod is pushed downward. At this time, the clamping part driven by the connecting rod extends into the corresponding accommodating groove to complete the fixing of the telescopic frame. Through the two connecting rods, the telescopic frame can be fixed more firmly on the frame. When the brake mechanism is set to slow down when pushing the transporter, the staff pulls the brake handle to complete the lifting of one end of the transmission member, and the other end of the transmission member moves downward to abut against the brake plate. The brake plate moves downward and drives the brake block on the brake plate to move downward. The brake block abuts and rubs against the tire below to complete the deceleration of the transporter. Through the elastic part that is set, when the staff releases the brake handle after completing braking, the elastic part that is always in a stretched state pulls one end of the transmission part downward, and the other end of the transmission part moves upward at this time, so that the brake pad is separated from the tire. There is no need to manually separate the brake pad and the tire, which reduces the time to release the braking state. BRIEF DESCRIPTION OF THE DRAWINGS
