Description

Technical Field

[0001] The invention relates to the technical field of rail transportation, and in particular to an anti-slip fixture and a long rail transport vehicle. Background Art

[0002] Rails are transported by transport vehicles to the line where the track is to be laid and unloaded from the transport vehicles by on-site construction workers. Generally, when unloading rails on a line with a slope of more than 10‰, the rails will slide along the slope, bringing great danger to on-site operations. Therefore, how to prevent rails from sliding when unloading on a line with a large slope has gradually become a research focus.

[0003] In the prior art, construction workers generally use locking pressure irons to prevent the rails from sliding during unloading. The locking pressure iron is composed of a lower pressure plate, a locking bolt and rubber. The lower pressure plate is in contact with the rail head of the rail. Rubber is provided on the contact surface of the lower pressure plate and the rail head of the rail. The locking bolt passes through the lower pressure plate and is threadedly connected to a locking beam provided on the bottom surface of the transport vehicle. Tightening the locking bolt reduces the distance between the lower pressure plate and the bottom surface of the transport vehicle, thereby increasing the friction between the rail and the lower pressure plate. When unloading, the tightening force of the locking bolt is adjusted to balance the friction force and the downward sliding force of the rail, thereby preventing the rail from sliding along the slope direction.

[0004] However, the tightening force cannot be accurately controlled when unloading rails using locking weights, and construction workers need to repeatedly adjust the tightening force of the locking bolts, resulting in low unloading efficiency. Summary of the invention

[0005] The embodiments of the present invention provide an anti-slip fixture and a long rail transport vehicle, which are used to solve the problem in the prior art that the tightening force cannot be accurately controlled when unloading rails using locking weights, and construction workers need to repeatedly adjust the tightening force of locking bolts, resulting in low unloading efficiency.

[0006] In a first aspect, an embodiment of the present invention provides an anti-slip clamp for fixing rails in long rail transport vehicles, comprising a first clamp and a second clamp connected by a detachable connecting piece, wherein the first clamp is clamped on a first rail to be unloaded to generate a friction force for limiting the sliding of the first rail; the second clamp is clamped on a second rail in a locked state to generate a friction force for limiting the movement of the first clamp and the first rail.

Fig. 9 is a schematic structural diagram of a first clamping arm; Fig.10 Schematic diagram of the structure of the third clamping arm.

[0064] Please refer to Figures 1 to 10 In the first aspect, the present embodiment provides an anti-slip fixture for fixing rails in a long rail transport vehicle, comprising a first fixture 1 and a second fixture 2 connected by a detachable connector 3, wherein the first fixture 1 is clamped on a first rail 4 to be unloaded to generate a friction force for limiting the sliding of the first rail 4; the second fixture 2 is clamped on a second rail 5 in a locked state to generate a friction force for limiting the movement of the first fixture 1 and the first rail 4.

[0065] Among them, the detachable connecting member 3 can specifically be a group of rings, including a first ring that can be connected to the first clamp and a second ring that can be connected to the second clamp. When installed and used, the first clamp is inserted into the first ring and locks the first ring, and the second clamp is inserted into the second ring and locks the second ring, thereby connecting the first clamp and the second clamp together. When dismantling, the first ring and the second ring can be removed; or, the detachable connecting member 3 can also be a bolt, and holes are provided on the first clamp 1 and the second clamp 2. The bolt passes through the two holes and is connected with a nut, thereby connecting the first clamp 1 and the second clamp 2 together. When dismantling, the nut can be loosened. The first fixture 1 can be specifically connected to the first rail 4 through a slot, in which the top of the first rail 4 is clamped, and by changing the size of the slot, different clamping forces are provided to clamp the first rail 4; or, two oppositely arranged clamping blocks can be provided on the first fixture 1, each of which is connected to one side of the first rail 4, and the first rail 4 is clamped by applying pressure to the two clamping blocks. In this embodiment, the second fixture 2 can also adopt a similar implementation structure to the first fixture 1, which will not be described in detail in this embodiment.

[0066] In addition, the first clamp 1 can meet the use requirements of different slopes by setting different preset values ​​of clamping force. For example, 10‰ can be used as the critical point. Between 0‰ and 10‰, the clamping force of the first clamp 1 can be the first clamping force, and between 10‰ and 20‰, the clamping force of the first clamp 1 can be the second clamping force. When unloading the rails, the construction personnel can set the clamping force of the first clamp 1 to a pre-designed preset value according to the current slope.

[0067] It should be noted that the rails are laid flat on the bearing surface of the long rail transport vehicle during transportation, and adjacent rails are placed in parallel. When unloading the rails, the construction workers unload them from both sides to the middle. The rail to be unloaded is regarded as the first rail 4 in this embodiment, and the rail adjacent to the first rail 4 is in a locked state during this unloading and is regarded as the second rail 5. When the first clamp 1 and the second clamp 2 are connected by the detachable connecting member 3, they should be spaced perpendicular to the extension direction of the rail. Of course, in this embodiment, the first rail 4 and the second rail 5 can also be two non-adjacent rails, as long as the first rail 4 during unloading is the rail to be unloaded and the second rail 5 is the rail that remains locked.

[0068] Specifically, the working principle of the anti-slip fixture provided in this embodiment is:

[0069] First, clamp the second fixture 2 on the second rail 5 and keep the position of the second fixture 2 always fixed on the second rail 5, clamp the first fixture 1 on the first rail 4, and the first fixture 1 is connected to the second fixture 2 through the detachable connector 3. The corresponding first fixture 1 is also fixed relative to the second rail 5 through the detachable connector 3 and the second fixture 2, so that the entire anti-slip fixture is always in a fixed state relative to the long rail transport vehicle during one unloading process. During unloading, the construction personnel first clamp the first fixture 1 on the outermost rail, that is, the first rail 4; and clamp the second fixture 2 on the rail adjacent to the first rail 1, that is, the second rail 5. After connecting the first fixture 1 and the second fixture 2 through the detachable connector 3, unlock the first rail 4. The first rail 4 is restricted by the friction force of the first fixture 1 and cannot slide, so as to avoid the first rail 4 from sliding or moving suddenly and causing a safety accident. The construction personnel unload the first rail 4 to the ground by dragging it to complete the unloading. After unloading is completed, the detachable connecting member 3 is removed, and the first clamp 1 and the second clamp 2 are released to prepare for the next unloading.

[0070] The anti-slip fixture provided in this embodiment is clamped on the second rail 5 by the second fixture 2. The second rail 5 remains locked during unloading, so that the second fixture 5 is fixed relative to the long rail transport vehicle. The first fixture 1 and the second fixture 2 are linked together by a detachable connector 3, so that the first fixture 1 is also fixed relative to the long rail transport vehicle, ensuring that the anti-slip fixture provided in this embodiment always remains fixed relative to the long rail transport vehicle when the rails are unloaded. During unloading, the first fixture 1 clamps the first rail 4 to be unloaded. After unlocking the first rail 4, the first rail 4 cannot slide at will due to the friction of the first fixture 1, avoiding sudden movement of the first rail 1 during unloading to cause safety accidents. During unloading, the construction workers drag the first rail 4 to the ground to complete the unloading. During the entire unloading process, the construction workers only need to clamp the first clamp 1 and the second clamp 2 on the first rail 4 and the second rail 5, and there is no need to repeatedly adjust the first clamp 1 and the second clamp 2, which greatly improves the work efficiency during unloading and solves the problem of low unloading efficiency caused by the construction workers repeatedly adjusting the locking pressure iron in the existing unloading method.

[0071] Further, on the basis of the above embodiment, in this embodiment, the first clamp 1 includes a first clamp arm 11 and a second clamp arm 12 which are relatively arranged on both sides of the first rail 4, and the first clamp arm 11 and the second clamp arm 12 are connected by a first threaded fastener 13, and the first threaded fastener 13 provides the first clamp arm 11 and the second clamp arm 12 with a positive pressure to clamp the first rail 4. The first clamp arm 11 and the second clamp arm 12 have a shape adapted to the shape of the rail, and after the first clamp arm 11 and the second clamp arm 12 are connected by the first threaded fastener 13, the positive pressure applied by the first clamp 1 to the first rail 4 can be increased by increasing the fastening force of the first threaded fastener 13, so that the structure is simple and the operation method is simple, which greatly improves the convenience of construction personnel in operating the anti-slip clamp. In addition, when tightening the first threaded fastener, the construction personnel can use a torque wrench, so as to accurately control the fastening force of the first threaded fastener 13, and then control the friction force of the first clamp 1 on the first rail 4.

[0072] It should be noted that, in this embodiment, the first clamp arm 11 and the second clamp arm 12 can adopt the same structure, which are mirror-symmetrical and connected by the first threaded fastener 3, thereby making the first clamp arm 11 and the second clamp arm 12 universal and avoiding waste of material and financial resources.

[0073] Further, on the basis of the above embodiment, in this embodiment, a nylon structure 6 is provided between the first clamp arm 11 and the second clamp arm 12 and the first rail 4. Specifically, a nylon layer is provided on the surface of the first clamp arm 11 in contact with the first rail 4, and a nylon layer is also provided on the surface of the second clamp arm 12 in contact with the first rail 4. The nylon can be made of a more common nylon material, for example, nylon obtained by ring-opening polymerization of lactam, or polymer nylon obtained by condensation polymerization of diamine and dibasic acid. This embodiment does not make other requirements for the specific type or brand of nylon used in the nylon structure 6. By providing the nylon structure 6, the contact area between the first clamp arm 11 and the second clamp arm 12 and the rail is increased, and the friction force of the first clamp arm 11 and the second clamp arm 12 on the first rail 4 is improved. In addition, nylon has good wear resistance, so that when the first rail 4 is pulled by the construction personnel and moves in the first fixture 1, the nylon is not easy to fall off or break, which effectively improves the durability of the first fixture 1.

[0074] Further, on the basis of the above embodiment, in this embodiment, the first rail 4 includes a first rail top 41, a first rail waist 42 and a first rail seat 43 forming an "I"-shaped structure, and the first clamp arm 11 and the second clamp arm 12 both include a first action portion 111 attached to one side of the first rail top 41, and a first connecting portion 112 and a pressing portion 113 connected to both ends of the first action portion 111, the first connecting portion 112 is located above the first rail top 41, and is used to install the first threaded fastener 13, and the pressing portion 113 presses against the first rail waist 42. Specifically, the two first action portions 111 are surrounded to form a first clamping groove, which surrounds the first rail top 41 of the first rail 4, and the two first action portions 111 are brought close to each other by continuously bringing the first clamp arm 11 and the second clamp arm 12 closer, thereby increasing the positive pressure applied by the first action portion 111 on the first rail top 41, and improving the friction force of the first fixture 1 on the first rail 4. In addition, the two pressing portions 113 press against the first rail waist 42, further increasing the friction force of the first fixture 1 on the first rail 4, and can be used to fix the first rail 4 in the horizontal direction to prevent it from shaking during unloading.

[0075] Optionally, a nylon structure 6 may be provided on the surface of the first action portion 111 facing the first rail 4 , and a nylon structure 6 may also be provided on the contact surface between the pressing portion 113 and the first rail 4 , thereby further increasing the friction force of the first fixture 1 on the first rail 4 .

[0076] In addition, a first protrusion 114 may be provided on one end of the first connecting portion 112 away from the first acting portion 111. Fig. 9When the first clamp arm 11 and the second clamp arm 12 are connected together, the two first protrusions 114 abut against each other, so that a certain distance is generated between the two first connection parts 112, and the same distance is also generated between the corresponding two first action parts 111. By continuously tightening the first threaded fastener 13, the distance is reduced, and the positive pressure applied by the first clamp arm 11 and the second clamp arm 12 to the first rail 4 is increased. The first protrusion 114 provides a larger adjustable range of the clamping force for the first fixture 1.

[0077] Further, on the basis of the above embodiment, in this embodiment, the long rail transport vehicle includes a locking beam 7, and the first fixture 1 includes a fixing plate 14 detachably mounted on the locking beam 7. When the rail is unloaded to the last rail, there is no rail in a locked state for the second fixture 2 to connect. At this time, the first fixture 1 is fixed to the locking beam 7 of the long rail transport vehicle through the fixing plate 14, so that the anti-slip fixture provided in this embodiment can also be used when the last rail is unloaded.

[0078] It should be noted that the cross section of the fixing plate 14 perpendicular to the extension direction of the first rail 4 can be a rectangular structure, and at least two bolt holes are provided on the upper and lower surfaces of the rectangular structure, and the bolts are connected to the locking beam 7 through the bolt holes, thereby avoiding the problem that the fixing plate 14 rotates around the bolt when only one bolt is provided, resulting in a malfunction in the use of the anti-slip fixture. The fixing plate 14 can be connected to the first fixture 1 by welding. Specifically, the fixing plate 14 can be welded to the side wall of the first clamp arm 11, and the distance from the upper surface to the lower surface of the fixing plate 14 is at least greater than the distance between the first rail top 41 and the first rail seat 43 of the first rail 4, so that when the first fixture 1 is fixed to the locking beam 7 through the fixing plate 14, the first fixture 1 has a space that can accommodate the first rail 4.

[0079] In addition, the bolt used in this embodiment can also be a positioning bolt with a rectangular head, and the bolt head and the screw rod form a "T"-shaped structure, see Figure 3 The locking beam 7 itself is provided with a "T"-shaped recessed groove for installing the locking weight. When unloading the rail, the locking weight needs to be removed to leave the "T"-shaped recessed groove vacant. By inserting the head of the positioning bolt into the "T"-shaped recessed groove, the fixing plate 14 can be fixed to the locking beam 7. Since the existing structure of the locking beam 7 is utilized, there is no need to drill additional holes on the locking beam 7, which improves the convenience of using the anti-slip fixture.

[0080] Further, on the basis of the above embodiment, in this embodiment, the second clamp 2 includes a third clamp arm 21 and a fourth clamp arm 22 which are relatively arranged on both sides of the second rail 5, and the third clamp arm 21 and the fourth clamp arm 22 are connected by a second threaded fastener 23, and the second threaded fastener 23 provides the third clamp arm 21 and the fourth clamp arm 22 with a positive pressure to clamp the second rail 5. The third clamp arm 21 and the fourth clamp arm 22 have a shape adapted to the shape of the rail. After the third clamp arm 21 and the fourth clamp arm 22 are connected by the second threaded fastener 23, the positive pressure applied by the second clamp 2 to the second rail 5 can be increased by increasing the fastening force of the second threaded fastener 23, so that the structure is simple and the operation method is simple, which greatly improves the convenience of construction personnel in operating the anti-slip clamp. The third clamp arm 21 can also adopt the same structure as the fourth clamp arm 22, so that the third clamp arm 21 and the fourth clamp arm 22 can be interchangeable, thereby improving the versatility of parts and avoiding wasting a lot of material and financial resources.

[0081] In addition, the first clamp arm 11 , the second clamp arm 12 , the third clamp arm 21 and the fourth clamp arm 22 may also adopt the same structure, so that the parts of the first clamp 1 and the parts of the second clamp 2 may also be interchangeable.

[0082] Further, on the basis of the above embodiment, in this embodiment, a rubber structure 8 is provided between the third clamp arm 21 and the fourth clamp arm 22 and the second rail 5. Specifically, a rubber layer can be provided on the contact surface between the third clamp arm 21 and the second rail 5, and similarly, a rubber layer can also be provided on the contact surface between the fourth clamp arm 22 and the second rail 5. The rubber deforms when subjected to force, thereby increasing the contact area between the third clamp arm 21 and the fourth clamp arm 22 and the second rail 5, thereby increasing the friction force of the second fixture 2 on the second rail 5, and preventing the second rail 5 from moving along the second fixture 2 during unloading, causing a safety accident.

[0083] It should be noted that this embodiment does not make any other requirements on the specific type of rubber material used for the rubber structure 8, as long as the rubber structure 8 can increase the friction of the second fixture 2 on the second rail 5. For example, the rubber structure 8 used in this embodiment can be natural rubber, nitrile rubber or hydrogenated nitrile rubber.

[0084] Further, on the basis of the above embodiment, in this embodiment, the second rail 5 includes a second rail top 51, a second rail waist 52 and a second rail seat 53 forming an "I" structure, and the third clamp arm 21 and the fourth clamp arm 22 each include a second action portion 211 attached to one side of the second rail top 51 and a second connecting portion 212 connected to the second action portion 211, and the second connecting portion 212 is located above the second rail top 51 and is used to install the second threaded fastener 23. The two second action portions 211 are arranged to form a second clamping groove, which surrounds the second rail top 51 of the second rail 5. By continuously bringing the third clamp arm 21 and the fourth clamp arm 22 closer, the two second action portions 211 are brought closer, thereby increasing the positive pressure applied by the second action portion 211 on the second rail top 51, and improving the friction force of the second fixture 2 on the second rail 5. A rubber structure 8 can be provided on the surface of the two second action portions 511 facing the second rail 5, thereby further increasing the friction force of the second fixture 2 on the second rail 5.

[0085] In addition, a second protrusion 213 may be provided on the end of the second connecting portion 212 away from the second acting portion 211. Fig.10 When the third clamp arm 21 and the fourth clamp arm 22 are connected together, the two second protrusions 213 abut against each other, so that a certain distance is generated between the two second connection parts 212, and the same distance is generated between the corresponding two second action parts 211. By continuously tightening the second threaded fastener 23, the distance is reduced, and the positive pressure applied by the third clamp arm 21 and the fourth clamp arm 22 on the second rail 5 is increased. The second protrusion 213 provides a larger adjustable range of the clamping force for the second clamp 2.

[0086] Further, on the basis of the above embodiment, in this embodiment, the detachable connector 3 includes a first connecting plate 31 and a second connecting plate 32 formed on the first fixture 1 and the second fixture 2, and a fixing pin 33 connecting the first connecting plate 31 and the second connecting plate 32. A first pin hole 311 is provided on the first connecting plate 31, and a second pin hole 321 corresponding to the position of the first pin hole 311 is provided on the second connecting plate 32. After the fixing pin 33 passes through the first pin hole 311 and the second pin hole 321, the first fixture 1 and the second fixture 2 can be connected together. When the detachable connector 3 needs to be removed, the fixing pin 33 can be pulled out, which greatly simplifies the process of installing the detachable connector 3 and further improves the unloading efficiency.

[0087] It should be noted that, in the present embodiment, at least two first pin holes 311 are provided, and the number of second pin holes 321 is consistent with that of the first pin holes 311, thereby avoiding the situation where the first fixture 1 or the second fixture 2 can rotate around the fixing pin 33 when only one first pin hole 311 and one second pin hole 321 are provided, thereby causing a malfunction in the use of the anti-slip fixture.

[0088] Optionally, the first connecting plate 31 can be integrally formed with the first fixture 1 by mold casting, or the first connecting plate 31 can be connected to the first fixture 1 by bolt connection or welding connection. Specifically, the first connecting plate 31 can be connected to the side wall of the first fixture 1 facing the second fixture 2. Similarly, the second connecting plate 32 can also be integrally formed with the second fixture 2, or connected by bolts or welding.

[0089] Furthermore, based on the above embodiment, this embodiment also provides a long rail transport vehicle, including the anti-slip fixture described in the above embodiment. The specific structure and implementation effect of the anti-slip fixture are as described in the above embodiment, and this embodiment will not repeat them.
