Pressing column device and schnabel car

Abstract

The present application discloses a pressing column device and a Schnabel car. The pressing column device comprises: a support box body used for being fixed on a Schnabel beam; a pressing column body slidably supported on the support box body; a driving screw in threaded fit with the pressing column body; and a driving device, wherein an output end of the driving device is transmittingly connected to the driving screw. In the pressing column device provided by the present application, the driving device supplies power and outputs torque, thereby driving the driving screw to rotate. The driving screw is in threaded fit with the pressing column body, and since the pressing column body is in sliding fit with the support box body and can only move linearly, the pressing column body reciprocates under the rotation of the driving screw, thereby realizing extension and retraction of the pressing column body, and thus achieving extension and retraction functions of the pressing column body. The present application can realize long-distance extension and retraction of the pressing column body without manual operation, thereby improving the convenience and safety of loading and unloading, and reducing the time required for loading and unloading.

Description

A column pressing device and clamping vehicle

[0001] This application claims priority to Chinese Patent Application No. 202411825541.8, filed on December 11, 2024, entitled "A Pillar Pressing Device and Clamping Cart", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of clamping vehicle technology, and more specifically, to a column pressing device and a clamping vehicle. Background Technology

[0003] Clamp cars are long and heavy freight railway cars with unique oversized transport capabilities, widely used in the transportation of large, extra-large, and other unconventional equipment. With the development of heavy industry and railway transportation, the requirements for clamp cars in railway transportation are becoming increasingly stringent.

[0004] As shown in Figure 1, the clamping vehicle has two half-cars. For ease of understanding, the two half-cars are defined as the first half-car and the second half-car. The first half-car and the second half-car are used to load goods. When the vehicle is running empty, the first half-car and the second half-car can be connected.

[0005] The first and second half-cars have basically the same structure and are arranged symmetrically. They generally include a bogie 100, a small underframe 400, a large underframe 200, and a clamp beam 300. The bogie 100 is located at the bottom of the small underframe 400, the large underframe 200 is supported on the two small underframes 400, and the clamp beam 300 is supported on the large underframe 200. The lower part of the clamp beam 300 has a lug plate, which, along with lug pins 501, connects to the cargo, thus clamping the cargo between the clamp beams 300 of the first and second half-cars. One of the clamp beams 300 of the first and second half-cars has a pressure column device on its upper part, while the other has a corresponding pad device. After the clamping car is unloaded, when the car is running empty, the lower part of the clamping beam 300 of the first half car and the second half car is connected by the car lug pin 501, and the upper part is supported by the pressure column device to prevent the clamping beam 300 from falling.

[0006] As shown in Figure 2, the prior art pressure column device 600 includes a pressure column body 601, a nut 602, a rotating screw 603, and a rotating handle 604. By rotating the rotating handle 604, the rotating screw 603 can be driven to rotate, thereby driving the pressure column body 601 to move in a straight line through the nut 602, thus adjusting the distance between the pressure column body 601 and the pad device on another clamp-shaped beam 300.

[0007] In the existing technology, the movement of the pressure column 601 is controlled by manually rotating the rotary handle 604. However, the travel L of the pressure column 601 is relatively large. Based on the pitch of the rotary screw 603 being 6mm, the rotary screw 603 needs to be rotated 50 to 60 times. Moreover, this is a high-altitude operation, which is very laborious and has poor safety.

[0008] Therefore, how to improve the convenience and safety of loading and unloading, and reduce the loading and unloading time, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0009] In view of this, the purpose of this application is to provide a pillar pressing device to improve the convenience and safety of loading and unloading vehicles and reduce the loading and unloading time;

[0010] Another object of this application is to provide a clamping vehicle having the above-mentioned pressure column device.

[0011] To achieve the above objectives, this application provides the following technical solution:

[0012] A column pressing device, comprising:

[0013] Support box, used to fix it to the clamp beam;

[0014] The pressure column is slidably supported on the support box;

[0015] The drive screw is threaded into the pressure column body;

[0016] A drive device, the output end of which is connected to the drive screw.

[0017] Optionally, in the above-mentioned column pressing device, the column pressing body is a square beam tube structure, and the drive screw is threadedly engaged with the column pressing body through a square nut;

[0018] The square nut is fixed inside the tube of the pressure column, and the drive screw is threadedly engaged with the square nut.

[0019] Optionally, the above-mentioned pressure column device further includes a connecting seat, which is used to fix to the clamp beam, and the drive screw is rotatably supported on the connecting seat;

[0020] The drive device is fixed on the connecting seat, and the output end of the drive device is connected to the drive screw.

[0021] Optionally, in the above-mentioned column pressing device, a column pressing head is provided at one end of the column pressing body located outside the support box.

[0022] Optionally, in the above-mentioned pressure column device, a plurality of sliders are fixed inside the support box, and the pressure column body slides in cooperation with the sliders.

[0024] The inner wall of the support box has an insert groove, and the slider is embedded in the insert groove.

[0025] The pressure column device provided in this application uses a drive unit to provide power and output torque, driving a drive screw to rotate. The drive screw is threadedly engaged with the pressure column body. Since the pressure column body is slidingly engaged with the support housing, it can only move in a straight line. Therefore, under the rotation of the drive screw, the pressure column body reciprocates, thereby extending and retracting the pressure column body, achieving its telescopic function. This application enables long-distance telescopic extension and retraction of the pressure column body without manual operation, improving the convenience and safety of loading and unloading, and reducing loading and unloading time.

[0026] A clamping vehicle, comprising:

[0027] Pliers-shaped beam;

[0030] The support member is used to support the lug pin during the assembly and disassembly of the lug pin. The support member is fixed to the lug plate and is located below the pin hole of the lug plate.

[0031] The support member is arranged on the target side of the lug plate, which is the downstream side of the lug pin disassembly direction.

[0032] Optionally, in the above-described clamping vehicle, the length of the support member satisfies the following condition: when the lug pin is in the disengaged state from the cargo, the pin cap of the lug pin is located above the support member; and / or,

[0033] The support member includes an upward-facing arc-shaped groove plate, and the arc-shaped groove plate is arranged parallel to the axis of the pin hole of the wheel plate.

[0034] Optionally, in the above-mentioned clamping vehicle, the auxiliary device for removing and installing the lug pin further includes a movable stop and / or a limiting stop;

[0035] The movable stop is detachably fixed to the support member. The movable stop is located at one end of the support member near the lug plate to prevent the lug pin from exiting the pin hole of the lug plate.

[0036] The limiting stop is located at the end of the support member away from the lug plate to prevent the lug pin from detaching from the support member.

[0037] The clamping vehicle provided in this application has the aforementioned column pressing device, and therefore possesses all the technical effects of the aforementioned column pressing device, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0047] The core of this application is to provide a pillar pressing device to improve the convenience and safety of loading and unloading vehicles and reduce the loading and unloading time;

[0048] Another key aspect of this application is to provide a clamping vehicle with the aforementioned pressure column device.

[0049] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0050] As shown in Figures 1, 3, and 4, the column pressing device disclosed in this application includes a support box 607, a column pressing body 601, a drive screw 606, and a drive device 605. The support box 607 is fixed to the clamp-shaped beam 300 and serves as the supporting foundation for the column pressing body 601, which is slidably supported on the support box 607. It should be noted that the column pressing body 601 can only move linearly along the support box 607 and cannot rotate; that is, the rotational freedom of the column pressing body 601 needs to be restricted.

[0051] The drive screw 606 is threadedly engaged with the pressure column 601. Specifically, a threaded hole that engages with the drive screw 606 can be directly provided on the pressure column 601, or a nut that engages with the drive screw 606 can be provided on the pressure column 601. As long as the drive screw 606 can be rotated, the pressure column 601 can reciprocate along the axis of the drive screw 606.

[0052] The output end of the drive device 605 is connected to the drive screw 606. The drive device 605 can be a hydraulic motor, a pneumatic motor, or a geared motor. The drive device 605 can drive the drive 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.

[0053] The pressure column device provided in this application is powered by a drive device 605, which outputs torque to drive a drive screw 606 to rotate. The drive screw 606 is threadedly engaged with the pressure column body 601. Since the pressure column body 601 is slidably engaged with the support housing 607, it can only move in a straight line. Therefore, under the rotation of the drive screw 606, the pressure column body 601 reciprocates, thereby extending and retracting the pressure column body 601, realizing its telescopic function. This application enables long-distance telescopic extension and retraction of the pressure column body 601 without manual operation, improving the convenience and safety of loading and unloading, and reducing loading and unloading time.

[0054] In this embodiment, the pressure column 601 is a square beam-tube structure, that is, the pressure column 601 is a square tube structure enclosed by a plate. Designing the pressure column 601 as a square beam-tube structure in this embodiment facilitates limiting the rotation of the pressure column 601. The drive screw 606 can be threaded into the pressure column 601 via a square nut 610, wherein the square nut 610 can be fixed inside the tube of the pressure column 601, and the drive screw 606 is threaded into the square nut 610. For example, the square nut 610 can be fixed to one end of the pressure column 601 near the drive device 605. Because the pressure column 601 is a tube structure, as the pressure column 601 moves linearly, the drive screw 606 can be accommodated inside the tube of the pressure column 601, reducing space occupation.

[0055] The support box 607 can also be designed as a rectangular box frame structure, which is formed by splicing multiple plates together to create a space in the middle for the pressure column 601 to slide. In this embodiment, both the pressure column 601 and the support box 607 are designed as square structures, which can be manufactured by welding the plates together. The manufacturing method is relatively simple and it is easy to restrict the rotation of the pressure column 601.

[0056] Furthermore, the pressure column device may also include a connecting seat 608, which is used to fix the clamp beam 300, and the drive screw 606 is rotatably supported on the connecting seat 608. The drive device 605 is fixed on the connecting seat 608, and the output end of the drive device 605 is connected to the drive screw 606 for transmission. The connecting seat 608 may be arranged on one side of the support housing 607 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. The output shaft of the drive device 605 and the drive screw 606 can be connected by a key to achieve torque transmission.

[0057] The pressure column 601 has a pressure head 609 at one end located outside the support box 607. The pressure head 609 is in contact with a pad device on another clamp-shaped beam 300. The pressure head 609 can be fixed to the end of the pressure column 601 with fasteners. If the pressure head 609 is damaged due to long-term contact and friction with the pad device, only the pressure head 609 needs to be replaced, without replacing the entire pressure column 601, thus reducing maintenance costs.

[0058] As shown in Figures 5 and 6, several sliders 611 are fixed inside the support box 607, and the pressure column 601 slides in conjunction with the sliders 611. Compared with the pressure column 601 directly contacting the inner wall of the support box 607, this reduces the contact area, lowers friction, and improves the smoothness of sliding. It also avoids the problem of sliding jamming caused by slight deformation of the support box 607.

[0059] The slider 611 can be fixed to the inner wall of the support box 607 using fasteners 612, as shown in Figure 5; alternatively, it can be fixed to the inner wall of the support box 607 using the method shown in Figure 6, where an insert groove is provided in the inner wall of the support box 607 and the slider 611 is embedded in the insert groove. The slider 611 can be fixed to the inner wall of the support box 607 in any feasible manner, and this embodiment does not limit the specific fixing method of the slider 611.

[0060] This application also discloses a clamping vehicle, which includes a clamping beam 300 and a pressure column device 600 disposed on the upper part of the clamping beam 300. The pressure column device 600 is the pressure column device disclosed in the above embodiment. Since it has the above-mentioned pressure column device 600, it has all the technical effects of the above-mentioned pressure column device 600, and will not be described in detail here.

[0061] As shown in Figure 7, the clamping vehicle may further include a lug pin removal and installation auxiliary device disposed on the lug plate 301 of the clamp beam 300. The lug pin removal and installation auxiliary device disclosed in this application embodiment is used to assist in the removal and installation of the lug pin 501. The lug pin removal and installation auxiliary device includes a support member 502.

[0062] During the assembly and disassembly of the lug pin 501, the support member 502 is used to support the lug pin 501. The support member 502 is fixed to the lug plate 301 of the clamp-shaped beam and is located below the pin hole of the lug plate 301. Specifically, the support member 502 can be directly welded to the lug plate 301 of the clamp-shaped beam, or it can be fixed to the lug plate 301 by fasteners. In this embodiment, the fixing method between the support member 502 and the lug plate 301 is not limited, as long as the relative fixing of the two can be achieved and the support member 502 can support the weight of the lug pin 501.

[0063] The support 502 needs to be positioned below the pin hole of the lug plate 301. It should be noted that "below" here does not mean directly below the pin hole; a certain degree of tilt is allowed, as long as the support 502 can provide support for the lug pin 501 after it is pulled out of the pin hole.

[0064] The support member 502 is arranged on the target side of the lug plate 301, which is downstream of the lug pin 501 in the disassembly direction. In other words, the support member 502 should be arranged on the side of the lug pin 501 with 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. Therefore, the end with the pin cap 5012 is the end of the lug pin 501 that is pulled out of the pin hole. In this embodiment, arranging the support member 502 on the end of the lug pin 501 with the pin cap 5012 can help support the lug pin 501, so that the lug pin 501 can be supported by the support member 502 before and after it is inserted into the pin hole, without the need for lifting equipment to remove it.

[0065] In this embodiment, a support member 502 is fixed on the lug plate 301. This support member 502 is positioned on the target side of the lug plate 301, specifically downstream of the lug pin 501 in the disassembly direction. When disassembling the lug pin 501 from the lug plate 301, simply push the lug pin 501 off the lug plate 301. As the lug pin 501 detaches from the lug plate 301, it gradually moves onto the support member 502. The support member 502 supports the portion of the lug pin 501 that has detached from the lug plate 301, eliminating the need for lifting equipment until the lug pin 501 is detached from the cargo connection. When assembling the lug pin 501, simply push the lug pin 501 supported on the support member 502 towards the lug plate 301 until it is fully inserted into the pin hole of the lug plate 301. This application does not require lifting equipment to insert and remove the lug pin 501, and does not require multiple people to operate, thus reducing the cost and time of disassembly and assembly.

[0066] In one specific embodiment of this application, the length of the support member 502 satisfies the following condition: when the lug pin 501 is in a state of being disconnected from the cargo, the pin cap 5012 of the lug pin 501 is located on the support member 502. Those skilled in the art will understand that when the lug pin 501 is in a state of being disconnected from the cargo, it can be completely detached from the pin hole of the lug plate 301, or a portion of the pin can remain within the pin hole, as long as it can complete the connection with the cargo.

[0067] A clamp beam typically has two lug plates 301, forming a cargo connection space between them. The cargo has a connecting part that can be inserted into this cargo connection space, and the connecting part of the cargo 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 part respectively, the connection between the cargo and the clamp beam is completed, thereby realizing the loading process of the cargo.

[0068] When disassembling the cargo, the lug pin 501 needs to be pulled out from the pin holes 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, after the lug pin 501 is completely pulled out from the pin holes 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 disengaged from the pin hole of the lug plate 301 near the support member 502, if it has already disengaged from the pin hole of the cargo connection part, the cargo can still be disconnected from the clamp beam. That is, this state of the lug pin 501 is still considered a state of being disconnected from the cargo.

[0069] It is evident that when disassembling goods, the lug pin 501 does not need to be completely pulled out, although it can be completely pulled out. Those skilled in the art can choose whether to completely pull out the lug pin 501 according to the actual scenario. Theoretically, as long as the lug pin 501 is disengaged from the pin hole of the goods connection part, it is sufficient.

[0070] The length of the support member 502 needs to be ensured so that when the lug pin 501 is detached from the cargo connection, the pin cap 5012 of the lug pin 501 is located on the support member 502. That is, after the lug pin 501 is detached from the pin hole of the cargo connection part, the pin cap 5012 at its end does not move out of the support member 502, so as to ensure that the support member 502 has a stable supporting force on the lug pin 501.

[0071] It should be noted that a portion of the structure of the lug pin 501 is allowed to extend beyond the support member 502, as long as the center of gravity of the lug pin 501 is above the support member 502, the lug pin 501 can be prevented from falling off the support member 502.

[0072] To facilitate the alignment of the lug pin 501 with the pin hole of the lug plate 301, in this embodiment, the support member 502 includes an upward-facing arc-shaped groove plate, and the arc-shaped groove plate is arranged parallel to the axis of the pin hole of the lug plate 301. After the lug pin 501 moves onto the arc-shaped groove plate, since the axis of the arc-shaped groove plate is parallel to the axis of the pin hole of the lug plate 301, it is easier to control the alignment of the lug pin 501 with the pin hole of the lug plate 301.

[0073] It should be noted that the axis of the arc-shaped groove plate is parallel to the axis of the pin hole of the lug plate 301, including the case where their axes are collinear, i.e., coaxially arranged. Even if the axis of the arc-shaped groove plate is below the axis of the pin hole of the lug plate 301, when pushing the lug pin 501 on the support 502 into the pin hole of the lug plate 301, the operator only needs to pry up the end of the lug pin 501 and then push it in. Compared with lifting equipment, it is still easier to complete the alignment and positioning process. Of course, if the end of the lug pin 501 is not completely out of the pin hole of the lug plate 301, it is not necessary to pry up the end of the lug pin 501, making the alignment and positioning process even easier.

[0074] Furthermore, the upper surface of the arc-shaped groove plate is in contact 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 collinear with the axis of the pin cap 5012 and the pin hole of the lug plate 301. With this 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 support effect is not good during the pulling process due to the existence of steps between the two.

[0075] In this embodiment, since the upper surface of the arc-shaped groove plate is in contact with the outer wall of the pin cap 5012 of the lug pin 501, the axis of the lug pin 501 is always coaxial with the pin hole of the lug plate 301 during the insertion and removal of the lug pin 501, which can eliminate the alignment and positioning process during insertion.

[0076] To prevent the lug pin 501 from detaching from the lug plate 301 during cargo transportation and to improve the safety of the transportation process, in a specific embodiment of this application, the lug pin removal and installation auxiliary device may further include a detachable movable stop 504 fixed to the support member 502. The movable stop 504 is disposed at one end of the support member 502 near the lug plate 301 to prevent the lug pin 501 from exiting the pin hole of the lug plate 301.

[0077] When removing the lug pin 501, the movable stop 504 must first be removed to prevent it from interfering with the removal. Similarly, when inserting the lug pin 501, the movable stop 504 must be removed to prevent it from interfering with the insertion process. After the lug pin 501 is fully inserted, the movable stop 504 is then reinstalled in its corresponding position to limit its movement and prevent it from moving outwards.

[0078] As can be seen from the above, the insertion and removal of the lug pin 501 requires the disassembly and assembly of the movable stop 504, which reduces the efficiency of the lug pin insertion and removal. Based on this, in this embodiment, one end of the movable stop 504 can be hinged to one side of the support member 502, and the other end can be detachably fixed to the other side of the support member 502 by fasteners.

[0079] When it is necessary to remove the lug pin 501, simply remove the fastener of the movable stop 504, then rotate the movable stop 504 so that it follows its hinge axis to a path away from the lug pin 501, preventing obstruction of the removal process. Similarly, when inserting the lug pin 501, the movable stop 504 must be rotated in the same manner to a path away from the insertion path, preventing it from interfering with the insertion process. After the lug pin 501 is fully inserted, rotate the movable stop 504 to the appropriate position and tighten the fastener.

[0080] It should be noted that the rotation direction of the movable stop 504 is not limited. It can be rotated horizontally as shown in Figure 3, or it can be designed to rotate vertically up and down, as long as it can rotate away from the insertion and removal path of the lug pin 501.

[0081] Both sides of the support member 502 are provided with connecting lugs extending outwards. One end of the movable stop 504 is hinged to one of the connecting lugs, and the other end is fixed to the other connecting lug by fasteners. In this embodiment, by providing connecting lugs on both sides of the support member 502, the installation of the movable stop 504 can be facilitated.

[0082] It should be noted that both ends of the movable stop 504 can also be detachably fixed to both sides of the support 502 by fasteners. When it is necessary to insert or remove the lug pin 501, both fasteners can be removed and the movable stop 504 can be removed; alternatively, only one fastener can be removed, and the other fastener can be loosened, so that the loosened fastener forms a hinge axis, allowing the movable stop 504 to rotate along the fastener. The removal process of the movable stop 504 is not limited to being completely removed from the support 502, as long as the movable stop 504 is removed from the insertion or removal path of the lug pin 501.

[0083] In one specific embodiment of this application, the auxiliary device for removing and installing the wheel lug pin may further include a reinforcing support 503 and / or a limiting stop 505. The reinforcing support 503 is used to fix itself to the wheel lug plate 301 of the clamp-shaped beam and is supported on the lower side of the support member 502. In this embodiment, by adding the reinforcing support 503, the installation strength of the support member 502 can be increased, preventing the problem of poor connection strength caused by an insufficient connection area between the support member 502 and the wheel lug plate 301.

[0084] A limiting stop 505 is disposed at the end of the support member 502 away from the lug plate 301 to prevent the lug pin 501 from detaching from the support member 502. In this embodiment, by setting the limiting stop 505, the risk of the lug pin 501 being directly pushed out of the support member 502 due to excessive force during the pulling out process can be prevented. The limiting stop 505 can prevent the lug pin 501 from continuing to move downstream, thereby limiting the farthest boundary in the pulling out path of the lug pin 501.

[0085] Furthermore, the limit stop 505 can also serve as a limiting boundary for the lug pin 501 to be in the state of being disconnected from the cargo. That is, when the lug pin 501 is pulled out, it can be pressed against the limit stop 505 as a basis for judging that the lug pin 501 has been disconnected from the cargo, so as to facilitate the operator to identify whether the cargo has been disconnected from the clamp beam.
