Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a mechanical manufacturing traction device. Background Technology

[0002] As a key piece of equipment in material handling, automated production lines, and warehousing logistics, the reliability and efficiency of multi-vehicle coordinated transportation of track-mounted mobile trolleys directly depend on the performance of the traction connection device. This device needs to achieve rapid docking and stable force transmission between trolleys, and maintain the safety of the connection under conditions such as high-frequency vibration, start-stop impact, and curved operation.

[0003] The existing traction connection devices for track trolleys mostly adopt simple pin-type or hook-type structures, which have the following prominent problems: First, manual installation requires precise alignment of the connection hole or hook position, which is cumbersome and time-consuming. Especially in heavy trolleys or in space-constrained conditions, it is difficult for a single person to operate, making it difficult to achieve rapid installation and docking at the traction connection point, which seriously affects the assembly efficiency of multi-car linkage systems. Second, there is a lack of effective anti-loosening design. When the trolley starts and stops frequently, or when the track is uneven or turns, the connecting parts are prone to loosening or even detaching due to vibration, causing safety hazards such as material falling or equipment collisions, which need to be further improved. Utility Model Content

[0004] The purpose of this utility model is to provide a mechanical manufacturing traction device, which is easy for manual and quick alignment and installation, reduces the difficulty of single-person operation and improves the efficiency of multi-vehicle linkage assembly, and has a reliable anti-loosening function. It can maintain stable connection under vibration, impact and curved operation conditions to ensure transportation safety, thus solving the problems in the prior art.

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

[0006] A mechanical manufacturing traction device includes a vertical plate, an installation mechanism disposed on the vertical plate, a bearing block fixed to one end of the vertical plate, a column fixed to the upper end of the bearing block, a rotating plate rotatably mounted on the side wall of the column, two vertical blocks fixed to the upper end of the column, a rotating column rotatably mounted through the two vertical blocks, and a rotating block rotatably mounted on the side wall of the rotating column. Rotating components are rotatably mounted on the ends of the two rotating blocks that are close to each other. A first connecting mechanism and a second connecting mechanism are respectively connected to the two rotating components.

[0007] A traction mechanism for connecting the first connecting mechanism and the second connecting mechanism is provided between the first connecting mechanism and the second connecting mechanism.

[0008] Preferably, the mounting mechanism includes a first bolt extending through the four corner edges of the upright plate and a first nut threaded onto the inner wall of the first bolt.

[0009] It is worth noting that the threaded connection of the bolt and the nut is simple to operate, without the need for complex tools, and a single person can complete the alignment and installation of the vertical plate and the trolley, greatly reducing the operation difficulty in the scene of space limitation or heavy trolley.

[0010] Preferably, the rotating assembly comprises a first groove body opened at one end of the two rotating blocks close to each other, a second groove body opened on the inner wall of the first groove body, a limiting column slidingly arranged on the inner wall of the first groove body, and a limiting disc fixed to one end of the limiting column, the side wall of the limiting disc and the inner wall of the second groove body are fitted, and the two ends close to each other of the two limiting columns are respectively fixed to the first connecting mechanism and the second connecting mechanism.

[0011] It is worth noting that the rotating assembly has the functions of bidirectional compensation and anti-dropping, on the one hand, the limiting column can slide in the first groove body, and the limiting disc can move in the second groove body, which can provide axial displacement compensation for the first / second connecting mechanism, adapt to the angle deviation of the trolley curve operation or the small displacement under the start-stop impact, and avoid component damage caused by rigid pulling; on the other hand, the fitting design of the limiting disc and the second groove body can prevent the limiting column from falling out of the rotating block, solving the safety hazard of easy loosening of the existing device due to vibration.

[0012] Preferably, the first connecting mechanism comprises a first U-shaped block fixed to one end of the limiting column away from the rotating block, a first through hole penetratingly opened on both sides of the first U-shaped block, a first column body slidingly arranged on the inner wall of the two first through holes, and two limiting rings fixed to the side wall of the first column body, and the two ends close to each other of the two limiting rings are respectively fitted with the two side surfaces of the first U-shaped block.

[0013] It is worth noting that the opening structure of the first U-shaped block facilitates the quick clamping of the traction mechanism, without the need for precise alignment of the hole position to complete the preliminary positioning, the sliding fit of the first column body and the first through hole has high fault tolerance, and a single person can easily insert the column body into the through hole, and at the same time, the close fitting of the limiting rings on both sides and the U-shaped block can firmly limit the axial movement of the first column body, avoiding the loosening of the column body when the trolley vibrates frequently or the track is not flat, ensuring the stable force transmission of the connecting part, and providing a guarantee for the reliable connection of the subsequent traction mechanism.

[0014] Preferably, the second connecting mechanism comprises a second U-shaped block fixed to one end of the other limiting column away from the rotating block, a second through hole penetratingly opened on both sides of the second U-shaped block, a second column body slidingly arranged on the inner wall of the two second through holes, and two second nuts threadedly mounted on the side wall of the second column body, and the second U-shaped block and the first U-shaped block are of the same structure.

[0015] It is worth noting that: the same structure design of the second U-shaped block and the first U-shaped block ensures the interchangeability of the components, reduces the types of spare parts, reduces the operation cost of "left and right distinction" during installation, further improves the single assembly efficiency, and the threaded connection of the second nut is stronger than the limiting ring of the first connecting mechanism. By tightening the nut, the clamping force can be adjusted according to the weight of the trolley, and it is suitable for different load working conditions. Moreover, the threaded connection can effectively resist loosening caused by vibration, and the anti-loosening effect is better than that of the existing hook type structure.

[0016] Preferably, a first screw hole is provided through the side wall of the second column, a second screw hole is provided through the upper end of the second nut, and the inner walls of the first screw hole and the second screw hole are threadedly connected with a threaded column. The side wall of the threaded column is fixedly connected with a welding ring, and the lower end of the welding ring is in close contact with the upper end of the second nut.

[0017] It is worth noting that: this structure realizes double locking and anti-loosening. The first locking is the threaded connection of the second nut and the second column, and the second locking is the further fixation of the threaded column to the nut and the column. After the threaded column penetrates the first and second screw holes, it can prevent the second nut from loosening under high-frequency vibration. When in use, ignite the welding ring to tightly weld the welding ring and the nut together, which limits the axial displacement of the threaded column and prevents it from falling off.

[0018] Preferably, the traction mechanism includes a first connecting block arranged between the first U-shaped block and the second U-shaped block. The two side faces of the first connecting block are in close contact with the two side faces of the inner wall of the first U-shaped block. One side of the first connecting block is provided with two third through holes, one of which is in close contact with the side wall of the first column, and the other of which is in close contact with the side wall of the second column. A plurality of evenly distributed tooth grooves are provided on the outer circumferential surface of the first connecting block. A rack is slidably arranged in the first U-shaped block. The rack and the tooth grooves are in meshing engagement. The end of the rack away from the first connecting block is fixedly connected with a stop block. The lower end of the stop block is in close contact with the upper end of the first U-shaped block. The side of the rack is provided with equally spaced scale grooves.

[0019] It is worth noting that: the first connecting block directly fits the first and second columns through the two third through holes, and precise alignment is not required to complete the connection of the two vehicles. Single-person operation efficiency is significantly improved. The meshing of the rack and the tooth groove can lock the position of the connecting block, prevent it from sliding under vibration, ensure stable force transmission, and intuitively display the engagement depth of the rack. The scale groove can be used to adjust the connection length according to the actual distance between the two vehicles without the need for repeated measurement. The stop block prevents the rack from falling off, further ensuring the reliability of the structure.

[0020] Preferably, the traction mechanism includes a rubber ring, a hollow ball, and a connecting column. The side walls of the first column and the second column are both provided with a rubber ring. The side wall of the rubber ring is fixedly connected with a hollow ball. The two hollow balls are fixedly connected with a connecting column at one end close to each other.

[0021] It is worth noting that: the rubber ring has elasticity, can absorb the energy generated by the trolley starting and stopping impact, high frequency vibration, reduce the damage of rigid collision to the connecting parts, and the friction of the rubber can prevent the ring from sliding on the column, and the basic anti-loose effect is achieved, the structure only needs to be installed by sleeving the rubber ring into the column, the operation is very simple, and one person can complete the connection in seconds, which greatly improves the assembly efficiency, and the elastic structure itself has anti-loose capability, ensuring the transportation safety.

[0022] Preferably, the traction mechanism comprises a second connecting block and a rubber block, the side walls of the first column and the second column are jointly sleeved with the second connecting block, and the second connecting block is fixed with the rubber block on both sides, and the second connecting block and the rubber block form an integral structure.

[0023] It is worth noting that: the one-piece design avoids the complexity of multi-component assembly, has higher structural strength, is not easy to damage, and has a long service life, the second connecting block is sleeved with two columns at the same time, and the two-car connection can be completed at one time, the rubber blocks on both sides are elastic, which can buffer vibration impact and reduce component wear on the one hand, and can tightly fit the inner walls of the first / second U-shaped blocks on the other hand, and the friction force is limited to prevent the connecting block from sliding, and the anti-loose effect is achieved.

[0024] Compared with the prior art, the utility model has the advantages that:

[0025] 1、The utility model effectively solves the problems of manual alignment difficulty and low assembly efficiency, the installation mechanism realizes single-person rapid fixation through bolts and nuts, without the need of complex tools, the opening design of the U-shaped block provides a fault tolerance space for sliding cooperation with the column, without the need of precise alignment, three kinds of traction mechanisms support rapid connection, especially the rubber ring type structure can complete assembly in seconds, greatly reducing the single-person operation difficulty and improving the multi-car linkage assembly efficiency;

[0026] 2、Through the setting of the traction mechanism, the design of the three kinds of traction mechanisms supports rapid connection installation, without the need of repeated measurement and adjustment, in the first traction mechanism, the first connecting block is directly sleeved with the first column and the second column through the two third through holes, without the need of aligning the hole positions, the rack slides along the inner wall of the first U-shaped block and is engaged with the tooth groove of the connecting block, the angle of the first connecting block can be adjusted, when the lower end of the stop block and the upper end of the first U-shaped block are attached, the third through hole and the second through hole are opposite, facilitating the rapid alignment and installation of the first connecting block and the second through hole;

[0027] 3、In the second traction mechanism, the rubber ring has elasticity and can be directly sleeved on the side wall of the first / second column, without the need of tools to complete the assembly, one person only needs to sleeve the two rubber rings into the columns of the two cars, and the hollow ball and the connecting column are automatically adapted to the distance between the two cars.

[0028] 4. In the third traction mechanism, the second connecting block is an integral structure, which can be simultaneously fitted with the first / second column, without the need for assembling multiple components in steps, the elasticity of the rubber block can compensate for slight positional deviations, and the fitting can be completed at once, thus being convenient to use.
