Description

Technical Field

[0001] The present invention relates to the technical field of clamping vehicles, and more specifically, to a column pressing device and a clamping vehicle. Background Art

[0002] Clamp trucks are long and large freight railway vehicles with unique over-limit transportation capabilities, and are widely used in the transportation of large and super-large and other unconventional equipment. With the development of heavy industry and railway transportation, the requirements for clamp trucks in railway transportation are getting higher and higher.

[0003] like Figure 1 As shown, the clamp car has two half-carriages. For ease of understanding, the two half-carriages are defined as the first half-carriage and the second half-carriage respectively. The first half-carriage and the second half-carriage are used to load goods. When the car is running empty, the first half-carriage and the second half-carriage can be connected.

[0004] The structures of the first half car and the second half car are basically the same, and the two are arranged symmetrically. The two generally include a bogie 100, a small chassis 400, a large chassis 200 and a clamp beam 300. The bogie 100 is arranged at the bottom of the small chassis 400, the large chassis 200 is supported on two small chassis 400, and the clamp beam 300 is supported on the large chassis 200. The lower part of the clamp beam 300 has a car ear plate, and the car ear plate and the car ear pin 501 are used to achieve connection with the goods, so that the goods are clamped between the clamp beams 300 of the first half car and the second half car. The upper part of the clamp beam 300 of one of the first half car and the second half car is provided with a column pressing device, and the other is provided with a pad device corresponding to the column pressing device. After the clamp truck is unloaded and is running empty, the lower parts of the clamp beams 300 of the first half of the truck and the second half of the truck are connected by the car ear pins 501, and the upper parts are supported by the pad device through the pressure column device to prevent the clamp beams 300 from falling.

[0005] like Figure 2 As shown, the prior art column pressing device 600 includes a column pressing body 601, a nut 602, a rotating screw 603 and a rotating handle 604. The rotating screw 603 can be driven to rotate by rotating the rotating handle 604, thereby driving the column pressing body 601 to move along a straight line through the nut 602, thereby adjusting the distance between the column pressing body 601 and the pad device on the other clamp beam 300.

[0006] In the prior art, the movement of the pressure column 601 is controlled by manually rotating the rotating handle 604, and the movement stroke L of the pressure column 601 is relatively large. According to the pitch of the rotating screw 603 of 6 mm, the rotating screw 603 needs to be rotated 50 to 60 times. In addition, the operation is very laborious and unsafe when working at high altitude.

[0007] Therefore, how to improve the convenience and safety of loading and unloading vehicles and reduce the time of loading and unloading vehicles is a problem that needs to be solved urgently by technical personnel in this field. Summary of the invention

DETAILED DESCRIPTION

[0024] The core of the present invention is to provide a column pressing device to improve the convenience and safety of loading and unloading vehicles and reduce the time of loading and unloading vehicles; Another core of the present invention is to provide a clamping vehicle having the above-mentioned column pressing device.

[0025] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the pressure column device disclosed in the embodiment of the present invention includes a support box 607, a pressure column 601, a drive screw 606 and a drive device 605. Among them, the support box 607 is used to be fixed on the clamp beam 300, and the support box 607 serves as a support base for the pressure column 601. The pressure column 601 is slidably supported on the support box 607. It should be noted that the pressure column 601 can only move linearly along the support box 607 and cannot rotate, that is, the rotational freedom of the pressure column 601 needs to be limited.

[0027] The driving screw 606 is threadedly matched with the pressure column 601. Specifically, a threaded hole that is threadedly matched with the driving screw 606 can be directly set on the pressure column 601, or a nut that is matched with the driving screw 606 can be set on the pressure column 601. As long as the driving screw 606 can be rotated to make the pressure column 601 reciprocate along the axis of the driving screw 606, it will be sufficient.

[0028] The output end of the driving device 605 is in transmission connection with the driving screw 606. The driving device 605 can be a hydraulic motor, a pneumatic motor, or a reduction motor. The driving device 605 can drive the driving screw 606 to rotate, thereby driving the pressure column 601 to move, so that the pressure column 601 can quickly fit with the pad device on the other clamp beam 300.

[0029] The column pressing device provided by the present invention provides power through the driving device 605, outputs torque, and drives the driving screw 606 to rotate. The driving screw 606 is threadedly matched with the column pressing body 601. Since the column pressing body 601 is slidably matched with the supporting box 607 and can only move in a straight line, the column pressing body 601 moves back and forth under the rotation of the driving screw 606, thereby realizing the extension and retraction of the column pressing body 601, and realizing the telescopic function of the column pressing body 601. The present invention can realize the long-distance telescopic extension of the column pressing body 601, does not require manual operation, improves the convenience and safety of loading and unloading vehicles, and reduces the time of loading and unloading vehicles.

[0030] In this embodiment, the pressure column 601 is a square beam tube structure, that is, the pressure column 601 is a square tube structure surrounded by a plate body. In this embodiment, the pressure column 601 is designed as a square beam tube structure, which can conveniently limit the rotation of the pressure column 601. The drive screw 606 can be threadedly matched with the pressure column 601 through the square nut 610, wherein the square nut 610 can be fixed in the tube body of the pressure column 601, and the drive screw 606 is threadedly matched with the square nut 610. For example, the square nut 610 can be fixed to one end of the pressure column 601 close to the drive device 605. The pressure column 601 is a tube structure, and as the pressure column 601 moves linearly, the drive screw 606 can be accommodated in the tube body of the pressure column 601, reducing space occupancy.

[0031] The support box 607 can also be designed as a rectangular box frame structure, which is spliced ​​by multiple plates and surrounded in the middle to form a space for the pressure column 601 to slide. In this embodiment, the pressure column 601 and the support box 607 are both designed as square structures, which can be prepared by welding the plates. The preparation method is relatively simple and it is easy to limit the rotation of the pressure column 601.

[0032] Furthermore, the column pressing device may further include a connection seat 608, which is used to be fixed on the clamp beam 300, and the drive screw 606 is rotatably supported on the connection seat 608. The drive device 605 is fixed on the connection seat 608, and the output end of the drive device 605 is transmission-connected to the drive screw 606. The connection seat 608 may be arranged on one side of the support box 607, and is used to support the drive device 605, so that the output shaft of the drive device 605 can be coaxial with the drive screw 606 at the same height, and the output shaft of the drive device 605 and the drive screw 606 can be connected by a key to achieve torque transmission.

[0033] A pressure column head 609 is provided at one end of the pressure column body 601 located outside the support box body 607, and is fitted with a pad device on another clamp beam 300 through the pressure column head 609. The pressure column head 609 can be fixed to the end of the pressure column body 601 by fasteners. When the pressure column head 609 is damaged due to long-term contact, friction and collision with the pad device, only the pressure column head 609 can be replaced without replacing the entire pressure column body 601, thereby reducing maintenance costs.

[0034] like Figure 5 and Figure 6 As shown, a plurality of sliders 611 are fixed in the support box 607, and the pressure column 601 slides with the sliders 611. Compared with the pressure column 601 directly contacting the inner wall of the support box 607, the contact area can be reduced, the friction force can be reduced, the smoothness of sliding can be improved, and the problem of sliding jamming caused by slight deformation of the support box 607 can also be avoided.

[0035] The slider 611 can be Figure 5As shown, it is fixed to the inner wall of the support box 607 by fasteners 612; Figure 6 In the illustrated solution, an embedding groove is provided on the inner wall of the support box 607, and the slider 611 is embedded in the embedding groove. The slider 611 can be fixed on the inner wall of the support box 607 by any feasible method, and the specific fixing method of the slider 611 is not limited in this embodiment.

[0036] The embodiment of the present invention further discloses a clamping vehicle, which includes a clamping beam 300 and a column pressing device 600 disposed on the upper part of the clamping beam 300. The column pressing device 600 is the column pressing device disclosed in the above embodiment. Since the column pressing device 600 is provided, all the technical effects of the column pressing device 600 are obtained, which will not be described in detail herein.

[0037] like Figure 7 As shown, further, the clamping vehicle may also include a lug pin disassembly and assembly auxiliary device arranged on the lug plate 301 of the clamp beam 300. The lug pin disassembly and assembly auxiliary device disclosed in the embodiment of the present invention is used to assist the disassembly and assembly of the lug pin 501, and the lug pin disassembly and assembly auxiliary device includes a supporting member 502.

[0038] During the disassembly and assembly process of the lug pin 501, the supporting member 502 is used to support the supporting member 502 of the lug pin 501. The supporting member 502 is used to be fixed on the lug plate 301 of the clamp beam and is located at the lower side of the pin hole of the lug plate 301. Specifically, the supporting member 502 can be directly welded to the lug plate 301 of the clamp beam, or can be fixed to the lug plate 301 by a fastener. In this embodiment, there is no limitation on the fixing method of the supporting member 502 and the lug plate 301, as long as the relative fixing of the two can be achieved and the supporting member 502 can support the weight of the lug pin 501.

[0039] The supporting member 502 needs to be arranged on the lower side of the pin hole of the ear plate 301. It should be noted that the lower side here does not only refer to the position directly below the pin hole. A certain degree of deflection is allowed as long as the supporting member 502 can provide support for the ear pin 501 after the ear pin 501 is pulled out of the pin hole.

[0040] The supporting member 502 is arranged on the target side of the lug plate 301, and the target side of the lug plate 301 is the downstream side of the disassembly direction of the lug pin 501. In other words, the supporting member 502 should be arranged on the side of the lug pin 501 having the pin cap 5012. After the lug pin 501 is inserted into the pin hole of the lug plate 301, it is limited by its pin cap 5012, so the end with the pin cap 5012 is the end of the lug pin 501 pulled out of the pin hole. In this embodiment, the supporting member 502 is arranged on the end of the lug pin 501 having the pin cap 5012, which can assist in supporting the lug pin 501, so that the lug pin 501 can be supported by the supporting member 502 before it is inserted into the pin hole and after it is pulled out of the pin hole, without the need for lifting equipment to lift it away.

[0041] In the embodiment of the present invention, a supporting member 502 is fixed on the lug plate 301, and the supporting member 502 is arranged on the target side of the lug plate 301, that is, on the downstream side of the disassembly direction of the lug pin 501. When the lug pin 501 is disassembled from the lug plate 301, it is only necessary to push the lug pin 501 out of the lug plate 301, and the lug pin 501 will gradually move to the supporting member 502 during the process of being separated from the lug plate 301. The supporting member 502 can support the part of the lug pin 501 that is separated from the lug plate 301, without the need for lifting equipment, until the lug pin 501 is separated from the cargo connection state. When assembling the lug pin 501, it is only necessary to push the lug pin 501 supported on the supporting member 502 in the direction of the lug plate 301 until the lug pin 501 is completely inserted into the pin hole of the lug plate 301. The present invention does not require lifting equipment to insert and remove the ear pin 501, and does not require multiple people to operate, thereby reducing the cost and time of disassembly and assembly.

[0042] In a specific embodiment of the present invention, the length of the supporting member 502 satisfies that when the ear pin 501 is in a state of being disconnected from the cargo, the pin cap 5012 of the ear pin 501 is located above the supporting member 502. It can be understood by those skilled in the art that when the ear pin 501 is in a state of being disconnected from the cargo, it can be completely disconnected from the pin hole of the ear plate 301, or a part of the pin section can be located in the pin hole, as long as the connection with the cargo can be completed.

[0043] A clamp beam generally has two lug plates 301, and a cargo connection space is formed between the two lug plates 301. The cargo has a connection portion that can be inserted into the cargo connection space, and the cargo connection portion also has a pin hole. After the lug pin 501 passes through the pin holes on the two lug plates 301 and the cargo connection portion, the cargo is connected to the clamp beam, and then the cargo loading process is realized.

[0044] When the cargo is disassembled, the lug pin 501 needs to be pulled out from the pin hole of the two lug plates 301 and the cargo connection part. At this time, the lug pin 501 is in a state of being disconnected from the cargo, and the cargo is disconnected from the clamp beam. As can be seen from the above content, after the lug pin 501 is completely pulled out from the pin hole of the two lug plates 301 and the cargo connection part, it will inevitably be in a state of being disconnected from the cargo; even if the end of the lug pin 501 has not been separated from the pin hole of the lug plate 301 close to the supporting member 502, if it has been separated from the pin hole of the cargo connection part, the cargo can also be disconnected from the clamp beam, that is, this state of the lug pin 501 still belongs to the state of being disconnected from the cargo.

[0045] It can be seen that when the goods are disassembled, the ear pin 501 does not need to be completely pulled out. Of course, it can be completely pulled out. Technical personnel in this field can choose whether to completely pull out the ear pin 501 according to the actual scenario. In theory, as long as the ear pin 501 is separated from the pin hole of the cargo connecting part, it will be sufficient.

[0046] The length of the supporting member 502 needs to ensure that when the ear pin 501 is in a state of being disconnected from the cargo connection, the pin cap 5012 of the ear pin 501 is located above the supporting member 502. That is, after the ear pin 501 is disconnected from the pin hole of the cargo connection portion, the pin cap 5012 at the end thereof does not move out of the supporting member 502, so as to ensure that the supporting member 502 has a stable supporting force on the ear pin 501.

[0047] It should be noted that part of the structure of the ear pin 501 is allowed to extend out of the supporting member 502 , and the ear pin 501 can be prevented from falling from the supporting member 502 as long as the center of gravity of the ear pin 501 is located above the supporting member 502 .

[0048] In order to facilitate the alignment of the lug pin 501 with the pin hole of the lug plate 301, in this embodiment, the supporting member 502 includes an arc-shaped slot plate with an opening facing upward, and the arc-shaped slot plate is arranged parallel to the axis of the pin hole of the lug plate 301. After the lug pin 501 moves to the arc-shaped slot plate, since the axis of the arc-shaped slot plate is parallel to the axis of the pin hole of the lug plate 301, it is easier to control the lug pin 501 to align with the pin hole of the lug plate 301.

[0049] It should be noted that the axis of the arc-shaped slot plate is parallel to the axis of the pin hole of the lug plate 301, including the case where the axes of the two are collinear, that is, the case where the two are coaxially arranged. Even if the axis of the arc-shaped slot plate is located below the axis of the pin hole of the lug plate 301. When pushing the lug pin 501 on the supporting member 502 into the pin hole of the lug plate 301, the operator only needs to tilt the end of the lug pin 501 and then push the lug pin 501 in. Compared with lifting with a lifting device, it is still easier to complete the alignment and positioning process. Of course, if the end of the lug pin 501 does not completely exit the pin hole of the lug plate 301, there is no need to tilt the end of the lug pin 501, and the alignment and positioning process is easier to complete.

[0050] Furthermore, the upper surface of the arc-shaped groove plate fits with the outer wall of the pin cap 5012 of the lug pin 501. The axis of the upper surface of the arc-shaped groove plate can be colinear with the axis of the pin cap 5012 and the pin hole of the lug plate 301. With such a configuration, when the lug pin 501 is pulled out, the pin cap 5012 slides along the upper surface of the arc-shaped groove plate, which can avoid the situation where the step between the two causes a poor support effect during the pulling out process.

[0051] In this embodiment, since the upper surface of the arc-shaped groove plate fits with the outer wall of the pin cap 5012 of the lug pin 501, the axis of the lug pin 501 can always be coaxial with the pin hole of the lug plate 301 during the insertion and removal of the lug pin 501, thereby eliminating the alignment and positioning process during insertion.

[0052] In order to prevent the lug pin 501 from being separated from the lug plate 301 during the cargo transportation process and improve the safety of the transportation process, in a specific embodiment of the present invention, the lug pin disassembly and assembly auxiliary device may further include a movable stopper 504 detachably fixed to the supporting member 502, and the movable stopper 504 is arranged at one end of the supporting member 502 close to the lug plate 301 to prevent the lug pin 501 from exiting the pin hole of the lug plate 301.

[0053] When pulling out the lug pin 501, the movable stopper 504 needs to be removed first to prevent the movable stopper 504 from affecting the pulling out of the lug pin 501. Similarly, when inserting the lug pin 501, the movable stopper 504 still needs to be removed to prevent the movable stopper 504 from affecting the insertion process of the lug pin 501. After the lug pin 501 is inserted into place, the movable stopper 504 is installed to the corresponding position so that the movable stopper 504 forms a limit for the lug pin 501 to prevent the lug pin 501 from moving in the direction of withdrawal.

[0054] As can be seen from the above content, during the insertion and removal process of the ear pin 501, the movable stopper 504 needs to be disassembled and assembled, which will reduce the insertion and removal efficiency of the ear pin 501. Based on this, in this embodiment, one end of the movable stopper 504 can be hinged to one side of the supporting member 502, and the other end can be detachably fixed to the other side of the supporting member 502 by a fastener.

[0055] When the lug pin 501 needs to be pulled out, only the fastener of the movable stopper 504 can be removed, and then the movable stopper 504 can be rotated so that the movable stopper 504 can be selected along its hinge axis to be pulled out of the lug pin 501 to prevent the lug pin 501 from being blocked during the pulling out process. Similarly, when inserting the lug pin 501, the movable stopper 504 still needs to be rotated to be away from the insertion path of the lug pin 501 in the above manner to prevent the movable stopper 504 from affecting the insertion process of the lug pin 501. After the lug pin 501 is inserted into place, the movable stopper 504 can be rotated to the corresponding position and the fastener can be locked.

[0056] It should be noted that the rotation direction of the movable stopper 504 is not limited and can be Figure 3 The horizontal left and right rotation shown can also be designed to rotate up and down in the vertical direction, as long as it can be turned away from the insertion and extraction path of the car ear pin 501.

[0057] Both sides of the support member 502 are provided with connecting ear plates extending outward, one end of the movable stopper 504 is hinged to one of the connecting ear plates, and the other end is fixed to the other connecting ear plate by a fastener. In this embodiment, by providing connecting ear plates on both sides of the support member 502, the installation of the movable stopper 504 can be facilitated.

[0058] It should be noted that both ends of the movable stopper 504 can also be detachably fixed to the two sides of the support member 502 by fasteners. When the lug pin 501 needs to be inserted or removed, both fasteners can be removed and the movable stopper 504 can be removed; or only one fastener can be removed and the other fastener can be loosened so that the loosened fastener forms a hinge axis so that the movable stopper 504 can rotate along the fastener. The removal process of the movable stopper 504 is not limited to being completely removed from the support member 502, as long as the movable stopper 504 can be removed from the insertion and removal path of the lug pin 501.

[0059] In a specific embodiment of the present invention, the lug pin disassembly and assembly auxiliary device may further include a reinforcing support seat 503 and / or a limit stopper 505. The reinforcing support seat 503 is used to be fixed on the lug plate 301 of the clamp beam and supported on the lower side of the supporting member 502. In this embodiment, by adding the reinforcing support seat 503, the installation strength of the supporting member 502 can be increased to prevent the problem of poor connection strength caused by too small a connection area between the supporting member 502 and the lug plate 301.

[0060] The limit stopper 505 is provided at one end of the support member 502 away from the lug plate 301 to prevent the lug pin 501 from being separated from the support member 502. In this embodiment, by providing the limit stopper 505, the risk of directly pushing the lug pin 501 out of the support member 502 due to excessive force during the process of pulling out the lug pin 501 can be prevented. The limit stopper 505 can prevent the lug pin 501 from continuing to move downstream, thereby limiting the farthest boundary of the lug pin 501 pulling out path.

[0061] Furthermore, the limit stop 505 can also serve as a limit boundary for the ear pin 501 to be in a state of being disconnected from the cargo. That is, when the ear pin 501 is pulled out, the ear pin 501 can be abutted against the limit stop 505 as a basis for judging that the ear pin 501 has been in a state of being disconnected from the cargo, so as to facilitate the operator to identify whether the cargo has been disconnected from the clamp beam.
