Summary of the Invention

[0004] The present invention mainly addresses the technical problems existing in the prior art and provides a non-powered parallel unit production line.

[0005] The above-mentioned technical problems of the present invention are mainly solved by the following technical solution: a non-powered parallel unit production line, including a transport track, a gantry crane for hoisting equipment is set at the top of the plant at the feeding end of the transport track, a plurality of crossbars are arranged horizontally inside the transport track, and the two ends of the crossbars are respectively installed on the transport track by connecting parts, the transport track is divided into a first station, a second station, a third station and a fourth station by the crossbars, and waiting stations are set between the first station and the second station, between the second station and the third station, and between the third station and the fourth station, and a trolley unloading area is set on the other side of the bottom of the gantry crane, and a plurality of unloading trolleys are parked in the trolley unloading area.

[0006] Preferably, the transport track includes two opposing track bodies. The top of each track body is triangular, and a bottom track is provided at the bottom of each track body. Multiple side positioning seats are provided on one side of the bottom track. The two sides of the bottom track are bent upward and cover the sides of the track body. An inner cavity is formed between the track body and the bottom track. Multiple support blocks are slidably arranged in the inner cavity. A middle slide is provided upward at the middle position of the bottom track, and the support blocks are slidably arranged on the middle slide.

[0007] Preferably, the support block includes a flat top portion and inclined sides that contact the inner wall of the track body, and the bottom of the support block is provided with a groove that slides against the middle slide rail.

[0008] Preferably, the feeding trolley includes a trolley base, an inner cavity is formed on the side of the trolley base, feeding wheels are provided at the four corners of the bottom of the trolley base, a second insertion hole is formed on the rear side of the feeding trolley, a insertion seat is inserted into the rear side of the trolley base, the insertion seat is inserted into the inner cavity and is set vertically corresponding to the first insertion hole, and insertion blocks are respectively provided at the top and bottom of the insertion seat to be inserted into the first insertion hole.

[0009] Preferably, a stop bracket is inserted into the rear side of the plug-in seat. The bottom of the stop bracket extends downward and bends backward to form a stop block. Multiple auxiliary rollers are rolled into the front side of the stop bracket corresponding to the stop block. Limiting frames are provided between the plug-in seat and the stop bracket. A spring is inserted between the two limiting frames.

[0010] Preferably, the front side of the trolley base is provided with multiple anti-collision blocks, the rear two ends of the trolley base are provided with positioning rods, the front two ends of the trolley base are provided with corresponding positioning rods and limiting frames are provided with a second insertion hole on one side of the front end of the limiting frame.

[0011] Preferably, the third station is provided with a single-sided removal station, and the fourth station is provided with a double-sided removal station. The single-sided removal station includes an auxiliary slide rail arranged laterally with the transport track. One end of the auxiliary slide rail extends outward from the outside of the transport track. A slide block is slidably provided on the top of the auxiliary track. The two sides of the slide block bend outward and extend outward. Multiple pulleys that roll in contact with the ground are inserted at the bends on both sides. The tops of the two slide blocks are provided with auxiliary tracks corresponding to the transport track. The auxiliary tracks and the transport track are aligned with each other and set at the same height.

[0012] Preferably, the auxiliary rail has a through groove at the corresponding slide block, and the auxiliary slide rail has a positioning block at the top left side of the middle of one side of the two transport rails.

[0013] The beneficial effects of this invention are as follows: The transport track is composed of a track body and a bottom track that work together. After the bottom track is fixed to the ground with bolts, it bends on both sides to cover the sides of the track body, thus protecting it from collapse. At the same time, multiple support blocks are inserted into the cavity between the bottom track and the track body. The inclined surfaces of the support blocks support the inner walls of the track body, increasing the overall strength of the track body. The contact surface between the top of the transport track and the feeding wheels of the unloading trolley is triangular. When the track intersects the plane, it can transport more smoothly and prevent the trolley from slipping off the track. The entire track is fixed with bolts, making subsequent disassembly more convenient and quick.

[0014] By setting up single-sided and double-sided removal stations on the transport track, and by setting up auxiliary slide rails laterally on the single-sided removal station, the auxiliary slide rail can be moved laterally outward, thereby moving the unloading trolley that has been transported to that location outward. This allows for the installation of parts outside the transport track. Due to installation needs and waiting requirements, assembly can be carried out outside the transport track. At the same time, a double-sided removal station is set up near the unloading station, which allows for the final installation step before pushing the material, and also adds a waiting area for pushing the material, increasing the efficiency of the next processing step.

[0024] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] Example: A non-powered parallel unit production line, such as Figures 1-8 As shown, the equipment includes a transport track 2. At the feeding end of the transport track 2, a gantry crane 1 for hoisting equipment is installed on the top of the factory building. Multiple horizontal bars 21 are arranged horizontally inside the transport track 2. The two ends of the horizontal bars 21 are respectively installed on the transport track 2 by connecting parts 22. The transport track 2 is divided into a first station 31, a second station 32, a third station 33, and a fourth station 34 by the horizontal bars 21. Waiting stations 37 are set between the first station 31 and the second station 32, between the second station 32 and the third station 33, and between the third station 33 and the fourth station 34. A trolley unloading area 38 is set on the other side of the bottom of the gantry crane 1, and multiple unloading trolleys 4 are parked in the trolley unloading area 38.

[0026] The transport track 2 includes two opposing track bodies 23. The top of the track body 23 is triangular, and the bottom of the track body 23 is provided with a bottom track 24. Multiple side positioning seats 26 are provided on one side of the bottom track 24. The two sides of the bottom track 24 are bent upward and cover the sides of the track body 23. An inner cavity is formed between the track body 23 and the bottom track 24. Multiple support blocks are slidably arranged in the inner cavity. A middle slide rail 241 is provided upward at the middle position of the bottom track 24. The support blocks are slidably arranged on the middle slide rail 241. The support blocks include a flat part 251 at the top and inclined parts 252 on both sides that contact the inner wall of the track body 23. The bottom of the support block has a groove 253 that slides with the middle slide rail 241.

[0027] The feeding trolley 4 includes a trolley base 41. An embedded cavity is annularly formed on the side of the trolley base 41. Feeding wheels 45 are provided at the four corners of the bottom of the trolley base 41. The interior of each feeding wheel 45 has an inner groove corresponding to the triangular shape at the top of the track body 23. A second insertion hole 431, penetrating vertically, is provided on the rear side of the feeding trolley 4. An insertion seat 46 is inserted into the rear side of the trolley base 41. The insertion seat 46 is inserted into the embedded cavity and is positioned vertically corresponding to the first insertion hole 410. Insertion blocks 461, which insert into the first insertion hole 410, are respectively provided at the top and bottom of the insertion seat 46. The rear side of the insertion seat 46 is further fitted with... A stop block 47 is provided. The bottom of the stop block 47 extends downward and bends backward to form a stop block 471. Multiple auxiliary rollers 472 are rolled and inserted into the front side of the stop block 471. Limiting frames 43 are provided between the insertion seat 46 and the stop block 47. Springs 49 are inserted between the two limiting frames 43. Multiple anti-collision impact blocks 42 are provided on the front side of the trolley base 41. Positioning rods 44 are provided at both ends of the rear side of the trolley base 41. Limiting frames 43 corresponding to the positioning rods 44 are provided at both ends of the front side of the trolley base 41. A second insertion hole 431 is opened on one side of the front end of the limiting frame 43.

[0028] The trolley base 41 has a connector 46 inserted into the rear side, and a stop bracket 47 extending downwards is inserted into the connector 46. It works in conjunction with the horizontal bar 21 set laterally on the transport track 2. When the trolley moves to the corresponding work station, the stop bracket 47 at the bottom can limit the movement of the trolley to the horizontal bar 21, preventing the front trolley from moving backward. At the same time, a spring 49 is set at the top between the stop bracket 47 and the connector 46. When the stop bracket 47 moves forward, the spring 49 can press down and reset the trolley. At the same time, multiple anti-collision impact blocks 42 are set on the front side of the trolley base 41. They can prevent collisions when multiple unloading trolleys 4 are stacked. When multiple unloading trolleys 4 are stacked and transported, the positioning rod 44 on the rear side of the front unloading trolley 4 is engaged with the limiting bracket 43 on the front side of the rear unloading trolley 4, which fixes the two unloading trolleys 4 in front and back, thus ensuring the stability of the bottom unloading trolley 4 when transporting materials of different sizes.

[0029] The third station 33 is equipped with a single-sided removal station, and the fourth station 34 is equipped with a double-sided removal station. The single-sided removal station includes an auxiliary slide rail 51 that is horizontally arranged with the transport track 2. One end of the auxiliary slide rail 51 extends outward from the outside of the transport track 2. A slide seat 53 is slidably arranged on the top of the auxiliary track 52. The two sides of the slide seat 53 bend outward and extend outward, and multiple pulleys 54 that roll in contact with the ground are inserted at the bends on both sides. The top of the two slide seats 53 is equipped with an auxiliary track 52 corresponding to the transport track 2. The auxiliary track 52 is aligned with the transport track 2 and is set at the same height. A through groove 521 is opened on the auxiliary track 52 corresponding to the slide seat 53. A positioning block 55 is set on the top of the auxiliary slide rail 51 located on the left side of one side of the two transport tracks 2.

[0030] The single-sided removal station is equipped with an auxiliary slide rail 51 laid on the transverse transport track 2, and a slide block 53 is slidably mounted on the auxiliary slide rail 51. An auxiliary track 52 matching the transport track 2 is installed on the slide block 53. When the material-carrying unloading trolley 4 arrives at this location, it moves laterally outwards and then assembles the material outside the transport track 2. Simultaneously, a positioning block 55 is installed on the auxiliary slide rail 51 of the single-sided removal station. This positioning block 55 is used to limit and reset the top auxiliary track 52 and the transport track 2 when the slide block 53 returns to its original position. The structure of the double-sided removal station is roughly the same as that of the single-sided removal station. The auxiliary slide rails are similar in structure. The length of 51 is doubled laterally on both sides, and the top positioning block 55 is replaced at both ends of the auxiliary slide rail 51. The reset of the slide seat 53 on its surface is detected manually. However, when the rear side moves out, the positioning block 55 achieves the anti-derailment effect after the movement. The single-sided movement station does not use limiters in the movement range. The main problem is that there are workers operating on one side in real time, so there is no need to worry about movement problems. When moving out, the outer limit wooden pin can be used for positioning. At the same time, when the double-sided movement station is moved out, there will sometimes be a waiting area effect for the material discharge station 35. Therefore, the positioning block 55 is set on the outside of the auxiliary slide rail 51 to achieve the anti-derailment effect.

[0031] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
