Description

Technical Field

[0001] This utility model relates to the field of logistics vehicle technology, and in particular to a transport trolley with protective function. Background Technology

[0002] Logistics trolleys, also known as cargo trolleys or cage trolleys, are unit mobile container equipment equipped with four casters for transporting and storing materials. They are commonly used in the logistics distribution of large supermarkets or the logistics turnover between processes in factories. In the wafer manufacturing and semiconductor production fields, trolleys are widely used as core logistics equipment in the material transportation of critical links such as plating pans and lithography machine production lines. In the production process, the transportation of materials, components, and goods is very important. Transport trolleys transport components to the lithography machine production line. As core handling equipment, the safety, stability, and ease of operation of trolleys are of paramount importance.

[0003] Most existing trolleys use fixed transport trays or open structures. During transportation, the goods are easily damaged or fall off due to collisions, vibrations or environmental factors. They lack active protection for the goods, which leads to damage. Especially in complex working conditions, it is difficult to ensure transportation stability. At the same time, the transport trays are usually fixed with bolts or clips. When replacing them, tools are needed to disassemble them one by one, which is time-consuming and labor-intensive, increases the difficulty of maintenance, and reduces work efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a protective transport trolley, which aims to solve the technical problems in the prior art, such as the trolley being prone to damage or falling of goods due to collisions, vibrations or environmental factors during transportation, lack of active protection for goods, resulting in damage, and the need to disassemble each item with tools when replacing goods, which is time-consuming and labor-intensive.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A protective transport trolley includes a base, a support frame, a support seat, and a transport mechanism. The support frame is connected to the base, and the support seat is vertically slidably connected to the support frame. The transport mechanism includes a mounting seat, a transport tray, and a protective cover. The mounting seat is connected to the side of the support seat facing away from the base. The mounting seat has a recessed mounting groove on the side facing away from the base. The transport tray is placed in the mounting groove. A limiting rod is slidably connected to the outer wall of the mounting seat. A limiting hole is formed on the outer wall of the transport tray. One end of the limiting rod passes through the outer wall of the mounting seat and is inserted into the limiting hole. A protective cover is provided on the side of the transport tray facing away from the base.

[0007] Furthermore, a base plate is provided at the bottom of the mounting base, and a baffle is connected to one end of the base plate facing away from the mounting base. A through hole is opened on the baffle, and the end of the limiting rod facing away from the transport tray passes through the through hole and is connected to the operating block.

[0008] Furthermore, a tension spring is sleeved on the limiting rod, and the two opposite ends of the tension spring are respectively connected to the operating block and the baffle.

[0009] Furthermore, the outer wall of the transport tray is provided with a number of positioning grooves, and the inner wall of the mounting base is provided with a number of positioning blocks that match the positioning grooves.

[0010] Furthermore, the protective cover has several first screw holes, and the transport tray has several second screw holes that match the first screw holes.

[0011] Furthermore, the protective cover has evenly distributed ventilation holes.

[0012] Furthermore, the support frame includes two rods, one end of which is connected to the base, and the ends of the two rods facing away from the base are connected by a crossbeam. The two opposite ends of the sliding seat are respectively sleeved on the two rods. Two fixed seats are provided on the side of the crossbeam facing away from the base. A fixed pulley is rotatably connected between the two fixed seats. A steel wire rope is provided on the fixed pulley. A winding roller is provided between the two rods. One end of the steel wire rope is connected to the winding roller, and the other end of the steel wire rope is connected to the sliding seat.

[0013] Furthermore, the steel wire rope is made of a non-elastic material.

[0014] Furthermore, a moving mechanism is provided on the base, and the moving mechanism includes several omnidirectional wheels.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the protective cover can effectively protect the transported goods, playing a proactive protection role. At the same time, through the matching of the positioning block and the positioning groove, the transport tray and the mounting base can be quickly positioned during installation, improving the assembly speed. By sliding the limiting rod connected to the mounting base, when the transport tray is placed in the mounting groove, the limiting rod is inserted into the limiting hole opened on the transport tray to complete the fixation of the transport tray. This avoids the problem that the goods are easily damaged or fall off due to collisions, vibrations or environmental factors during the transportation process, and that the lack of proactive protection for the goods leads to damage. It also avoids the technical problems of needing to disassemble each item with tools when replacing them, which is time-consuming and labor-intensive. Attached Figure Description

[0028] Please see Figures 1 to 5 This utility model provides a protective transport trolley, comprising a base 1, a support frame 2, a support seat 3, and a transport mechanism 11. The support frame 2 is connected to the base 1, and the support seat 3 is vertically slidably connected to the support frame 2. The transport mechanism 11 includes a mounting seat 111, a transport tray 112, and a protective cover 119. The side of the support seat 3 facing away from the base 1 is connected to the mounting seat 111. The side of the mounting seat facing away from the base 1 is recessed to form a mounting groove, and the transport tray 112 is placed in the mounting groove. A limiting rod 116 is slidably connected to the outer wall of the mounting seat 111, and a limiting hole 118 is opened on the outer wall of the transport tray 112. One end of the limiting rod 116 passes through the outer wall of the mounting seat 111 and is inserted into the limiting hole 118. The protective cover 119 is provided on the side of the transport tray 112 facing away from the base 1.

[0029] The mounting base 111 has a base plate at its bottom. One end of the base plate facing away from the mounting base 111 is connected to a baffle 115. A through hole is opened on the baffle 115. The end of the limiting rod 116 facing away from the transport tray 112 passes through the through hole and is connected to the operating block.

[0030] A tension spring 117 is sleeved on the limiting rod 116. The two opposite ends of the tension spring 117 are respectively connected to the operating block and the baffle 115. Due to the tension of the tension spring 117, the limiting rod 116 is normally placed in the limiting hole 118. When the limiting rod 116 is pulled outward, the tension rod 116 can be disengaged from the limiting hole 118, thereby achieving the effect of quickly disassembling the transport tray 112.

[0031] The outer wall of the transport tray 112 is provided with a plurality of positioning grooves 114, and the inner wall of the mounting base 111 is provided with a plurality of positioning blocks 113 that match the positioning grooves 114. By matching the positioning grooves 114 with the positioning blocks 113, the placement and removal of the transport tray 112 can be done accurately and quickly, saving time.

[0032] The protective cover 119 has a plurality of first screw holes 121, and the transport tray has a plurality of second screw holes 122 that match the first screw holes, so that the transport tray 112 and the protective cover 119 are connected in a closed manner, which avoids the goods from becoming unstable and damaged due to bumps during the transportation of goods.

[0033] The protective cover 119 has evenly distributed ventilation holes, which facilitates the observation of the goods during transportation and allows for timely detection of the condition of the goods in the transport tray 112, enabling timely response and handling.

[0034] The support frame 2 includes two rods, one end of which is connected to the base 1. The ends of the two rods facing away from the base 1 are connected by a crossbeam. The two opposite ends of the sliding seat 104 are respectively sleeved on the two rods. Two fixed seats 106 are provided on the side of the crossbeam facing away from the base 1. A fixed pulley 105 is rotatably connected between the two fixed seats 106. A steel wire rope 103 is provided on the fixed pulley 105. A winding roller 102 is provided between the two rods. One end of the steel wire rope 103 is connected to the winding roller 102, and the other end of the steel wire rope 103 is connected to the sliding seat 104. Specifically, a stepper motor 101 is used to... The winding roller 102 is driven to rotate, winding or releasing the wire rope 103, thereby driving the sliding seat 104 to move up and down along the outer wall of the support frame 2. The movement trajectory of the sliding seat 104 is guided by the fixed pulley 105, so that the sliding seat 104 can drive the transport tray 112 on the top of the support 3 to move up and down in a straight line, ensuring a smooth lifting process for transporting goods. When it is necessary to adjust the height of the transport tray 112, the stepper motor 101 precisely controls the speed and stroke of the winding roller 102 according to a preset program, thereby achieving precise lifting and positioning of the transport tray 112.

[0035] The steel wire rope 103 is made of non-elastic material, which is used to reduce the shaking of the transport tray caused by the shaking of elastic materials during transportation, and is more conducive to the stability and safety of cargo transportation.

[0036] The base 1 is provided with a moving mechanism, which includes several casters.

[0037] Specifically, during use, the support frame 2 and the support base 3 provide a stable bearing platform for the transport mechanism 11. The transport tray 112 in the transport mechanism 11 engages with the positioning block 113 in the mounting base 111 via the positioning groove 114, achieving precise positioning of the transport tray 112 within the mounting base 111 and improving the stability of the fixation. The limiting hole 118 on the surface of the transport tray 112 is connected to the protective cover 119 via the fixing bolt 120, forming a closed protective structure to prevent goods from falling off the transport tray 11. If the tray falls from the mounting base 111, the limiting rod 116, under the elastic force of the tension spring 117, is normally inserted into the limiting hole 118 of the transport tray 112, forming an axial lock. When the transport tray 112 needs to be replaced, the limiting rod 116 is pulled to overcome the elastic force of the tension spring 117 and slide, so that the limiting rod 116 disengages from the inside of the limiting hole 118. The entire process does not require disassembling the protective cover 119 or the fixing bolt 120, and the transport tray 112 can be quickly removed from the mounting base 111, improving maintenance efficiency.
