[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0037] Example 1
[0038] When transporting glass substrates within the factory area, rail transport vehicles are generally used. Figure 1 This is a structural schematic diagram of a rail transport vehicle, such as... Figure 1 As shown, the rail transport vehicle 100 includes a vehicle body 101. The vehicle body 101 is rotatably equipped with running wheels 102 and guide wheels 103. The running wheels 102 are used for the movement of the vehicle body 101, while the guide wheels 103 can ensure that the vehicle body 101 is located between two spaced tracks 104 to ensure stability when transporting glass substrates.
[0039] Specifically, the track 104 includes a base plate 1041, a side plate 1042, and a top plate 1043 connected in sequence to form a guide groove between the base plate 1041, the side plate 1042, and the top plate 1043. The running wheels 102 of the track transport vehicle 100 are located in the guide groove and roll on the base plate 1041. The guide wheel 103 is disposed in the guide groove and can roll against the side plate 1042. When the track transport vehicle 100 moves between the two tracks 104, when the vehicle body 101 deviates between the two tracks 104, the guide wheel 103 can abut against the side plate 1042 to ensure that the deviation of the vehicle body 101 is not too large. The guide wheel 103 can also make the vehicle body 101 turn along the track 104.
[0040] However, the auxiliary wheels are small in size and their screws are easily damaged. Operators need to remove the damaged auxiliary wheels and manually push the vehicle body 101 to move. During the process, the vehicle body 101 sways from side to side, causing it to deviate and collide with the rails 104 on both sides, increasing the resistance to the forward movement of the vehicle body 101. This greatly increases the difficulty for operators to push the vehicle body 101 and affects production efficiency.
[0041] To address the aforementioned issues, this embodiment provides a traction fixture that can be detachably connected to the rail transport vehicle 100 to ensure that the vehicle body 101 does not collide with the rail 104 when the guide wheel 103 of the rail transport vehicle 100 is damaged.
[0042] Figure 2 This is a structural diagram of the rail transport vehicle and the traction fixture. Figure 3 This is a schematic diagram of the traction fixture. (For example...) Figure 2 and Figure 3 As shown, the traction fixture includes a bracket 1 and at least one guide mechanism 2. The bracket 1 is disposed between two tracks 104 of the rail transport vehicle 100. The bracket 1 is provided with a connecting structure, which is detachably connected to the rail transport vehicle 100. The guide mechanism 2 includes a guide rod 21 and an auxiliary guide wheel 22. The guide rod 21 is disposed on the bracket 1, and the auxiliary guide wheel 22 is rotatably disposed on the guide rod 21. The auxiliary guide wheel 22 can roll and abut against one of the tracks 104.
[0043] The bracket 1 of the traction fixture is detachably connected to the rail transport vehicle 100. When the guide wheel 103 of the rail transport vehicle 100 is damaged, the traction fixture can be assembled onto the body 101 of the rail transport vehicle 100 through the bracket 1. At this time, the auxiliary guide wheel 22 of the guiding mechanism 2 can replace the damaged guide wheel 103 and abut against the rail 104 on the damaged side of the guide wheel 103, so that the auxiliary guide wheel 22 can play the role of the guide wheel 103 of the rail transport vehicle 100, guide the body 101 of the rail transport vehicle 100, and ensure that the body 101 is between the two rails 104.
[0044] Preferably, the traction fixture includes two guiding mechanisms 2. The auxiliary guide wheel 22 of one guiding mechanism 2 can roll and abut against one track 104, and the auxiliary guide wheel 22 of the other guiding mechanism 2 can roll and abut against another track 104. That is to say, the traction fixture can be used regardless of whether the guide wheel 103 on the left or right side of the rail transport vehicle 100 is damaged, which greatly improves the applicability of the traction fixture. In addition, the auxiliary guide wheels 22 are provided on opposite sides of the bracket 1, which also makes the auxiliary guidance position of the traction fixture on the vehicle body 101 symmetrical, thereby improving the stability of the vehicle body 101.
[0045] This traction fixture enables the rail transport vehicle 100 with damaged guide wheels 103 to travel normally between two tracks 104, preventing the vehicle body 101 from colliding with the track 104, reducing forward resistance. Operators can manually push the vehicle body 101 or control the movement of the vehicle body 101 through the control system, which is convenient to operate and reduces the impact on production efficiency.
[0046] In this embodiment, the connection structure includes a connection hole 11 formed in the bracket 1, and the rail transport vehicle 100 is provided with a first connecting post 105. The connection hole 11 is sleeved on the first connecting post 105 and detachably connected to the first connecting post 105. The first connecting post 105 is an inherent structure of the rail transport vehicle 100. Using the first connecting post 105 to fix the bracket 1 can save costs and is more convenient.
[0047] To improve the stability between the bracket 1 and the rail transport vehicle 100, the connection structure also includes a first screw 12. The first screw 12 passes through the bracket 1 and is threadedly connected to the bracket 1. The first screw 12 can abut against the first connecting post 105, thereby locking the first connecting post 105 to the bracket 1.
[0048] In this embodiment, the rail transport vehicle 100 includes an anti-collision sensor, which is fixed to the vehicle body 101 by a fixing bolt. Its main function is to prevent the vehicle body 101 from colliding with other structures. Therefore, the anti-collision sensor is set at the front end or rear end of the vehicle body 101, and the bracket 1 can be set on the fixing bolt of the anti-collision sensor.
[0049] In this embodiment, the bracket 1 is provided with at least one anti-rotation pin 13, and the front and rear ends of the vehicle body 101 are respectively provided with anti-rotation holes 106. When the bracket 1 is fixedly connected to the vehicle body 101, the anti-rotation pin 13 passes through the anti-rotation hole 106 at the corresponding end to ensure the stability between the bracket 1 and the vehicle body 101.
[0050] In this embodiment, the guide rod 21 is slidably connected to the bracket 1 to adjust the distance between the auxiliary guide wheel 22 and the track 104, so that the operator can change the offset of the vehicle body 101 between the two tracks 104 according to the actual situation, thereby ensuring that the vehicle body 101 can move smoothly.
[0051] Preferably, the traction fixture further includes a locking element 3, which is disposed on the guide rod 21 and configured to lock the relative position between the bracket 1 and the guide rod 21. The locking element 3 is used to lock the guide rod 21, ensuring that the position of the guide rod 21 remains stable after the operator has adjusted it to the correct position, preventing the guide rod 21 from moving and causing the auxiliary guide wheel 22 to fail to provide guidance to the vehicle body 101. The locking element 3 is a second screw, which passes through the guide rod 21 and is threadedly connected to it. The locking element 3 abuts against the bracket 1 to lock the guide rod 21.
[0052] Figure 4 This is a structural diagram of the guiding mechanism. (For example...) Figure 3 and Figure 4 As shown, the traction fixture also includes a drive assembly, which includes a drive gear 4 and a guide rod 21 with a toothed segment 2111. The drive gear 4 is rotatably mounted on the bracket 1 and meshes with the toothed segment 2111. The operator can drive the guide rod 21 to move through the drive gear 4, thereby adjusting the distance between the guide wheel 22 and the track 104. The operation is simple and the adjustment accuracy is high.
[0053] It is worth noting that the guide rods 21 of both guide mechanisms 2 have toothed segments 2111, and both guide rods 21 mesh with the drive gear 4 and are symmetrically distributed on both sides of the drive gear 4. When the drive gear 4 rotates, the two guide rods 21 move in opposite directions at the same time, so that the operator can control the distance between the two auxiliary guide wheels 22 and the corresponding track 104 at the same time.
[0054] The drive assembly also includes a handwheel, which is coaxially connected to the drive gear 4. The operator can manually control the rotation of the drive gear 4 through the handwheel. The drive assembly also includes a drive motor, which is connected to the drive gear 4. The drive motor automatically controls the movement of the guide rod 21.
[0055] In this embodiment, the guide rod 21 includes a main rod 211 and a telescopic rod 212. The telescopic rod 212 is slidably connected to the main rod 211. The main rod 211 is mounted on the bracket 1. The auxiliary guide wheel 22 is rotatably mounted on the telescopic rod 212. An elastic element 213 is provided between the telescopic rod 212 and the main rod 211. The elastic element 213 drives the telescopic rod 212 to move towards the track 104.
[0056] In other words, when the auxiliary guide wheel 22 abuts against the side plate 1042 of the track 104, the swing of the car body 101 can compress the elastic element 213, so that the elastic element 213 can buffer the car body 101. The elastic element 213 can also buffer the contact between the auxiliary guide wheel 22 and the track 104. Moreover, with the adjustment of the guide rod 21, the pressure between the auxiliary guide wheel 22 and the side plate 1042 of the track 104 can be changed, thereby changing the amplitude of the car body 101's sway.
[0057] Preferably, the elastic element 213 is a spring, which is sleeved on the telescopic rod 212. The side wall of the telescopic rod 212 has a first limiting part 2121 protruding from it, and the two ends of the spring abut against the main rod 211 and the first limiting part 2121, respectively. The telescopic rod 212 can provide support for the spring, prevent the spring from twisting or bending, and ensure that the spring can only extend and retract axially, while the first limiting part 2121 is used to abut against the ends of the spring.
[0058] In this embodiment, the main rod 211 is provided with a second limiting part, and the side wall of the telescopic rod 212 is provided with a third limiting part 2122. During the process of the elastic member 213 driving the telescopic rod 212 to move, the second limiting part and the third limiting part 2122 abut against each other to ensure that the telescopic rod 212 will not separate from the main rod 211 under the drive of the spring, thus ensuring the integrity of the guide rod 21. At the same time, it is also convenient for the operator to control the two telescopic rods 212 to move closer to each other so that the traction fixture can be placed between the two tracks 104.
[0059] like Figure 3 and Figure 4 As shown, the main rod 211 also includes a sliding section 2112 connected to the toothed section 2111. The telescopic rod 212 passes through the sliding section 2112. One end of the spring abuts against one side of the sliding section 2112. The sliding section 2112 forms a second limiting part, and the third limiting part 2122 abuts against the other side of the sliding section 2112.
[0060] Example 2
[0061] This embodiment is based on Embodiment 1, and the structure of the traction fixture has been improved.
[0062] Figure 5 This is a schematic diagram of the traction fixture in this embodiment. Figure 5As shown, the connection structure also includes a second connecting post 14, which is detachably inserted through the connecting hole 11 and detachably connected to the rail transport vehicle 100. It is worth noting that only one end of the vehicle body 101 (front or rear) may be equipped with an anti-collision sensor. In this case, if the guide wheel 103 at the other end is damaged, the second connecting post 14 can be used to connect the bracket 1 to the vehicle body 101, and the bracket 1 can be connected to the second connecting post 14 to connect the bracket 1 to the vehicle body 101, thus ensuring the normal use of the traction fixture.
[0063] Preferably, the second connecting post 14 has a threaded section, which is threadedly connected to the threaded hole of the vehicle body 101. The second connecting post 14 passes through the connecting hole 11 and is locked by the first screw 12.
[0064] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
