[0050] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] like Figure 1 , Figure 2 As shown, a cable conveyor provided by an embodiment of the present invention is used for conveying cables, and includes a base frame assembly 100, a support assembly 200 and two crawler assemblies 300.

[0054] like Figure 3As shown, the chassis assembly 100 is configured to be preassembled into an independent module. It is understandable that the chassis assembly 100 is assembled from a variety of parts, and the chassis assembly 100 can be preassembled into an independent module.

[0055] The support assembly 200 is configured to be preassembled into an independent module. It is understandable that the support assembly 200 is assembled from a variety of parts, and the support assembly 200 can be preassembled into an independent module.

[0056] Each track assembly 300 is configured to be preassembled into an independent module. It is understandable that the track assembly 300 is assembled from a variety of parts, and the track assembly 300 can be preassembled into an independent module.

[0057] like Figures 1 to 3 As shown, the support assembly 200 is detachably disposed on the base frame assembly 100, and the two track assemblies 300 are detachably connected to the support assembly 200, and the two track assemblies 300 are arranged side by side and spaced apart, one on the left and one on the right, and the cable can be clamped between the two track assemblies 300 and transported by the cable conveyor in a working state.

[0058] In the cable conveyor of the present invention, the chassis assembly 100, the support assembly 200 and the track assembly 300 are modularly designed. During transportation, the pre-assembled chassis assembly 100, the support assembly 200 and the track assembly 300 can be transported separately and then assembled on site. For narrow areas, such as wellheads, the entire cable conveyor may not be accessible, and the purpose of transportation can be achieved by transporting the chassis assembly 100, the support assembly 200 and the track assembly 300 of the cable conveyor separately, thereby improving the adaptability and flexibility of the equipment in complex terrain and narrow space. In addition, the track assembly 300, the support assembly 200 and the chassis assembly 100 can be disassembled, making the maintenance and upgrading of the equipment easier.

[0059] Combination Figure 1 and Figure 4 It can be understood that a wire-passing channel is defined between the two track assemblies 300, and the cable is placed in the wire-passing channel and clamped by the two track assemblies 300; the chassis assembly 100 includes a chassis 110, and two cable limiting devices 120 arranged on the chassis 110, the two cable limiting devices 120 are arranged at intervals in the front and rear directions, and the two cable limiting devices 120 are respectively located on the front and rear sides of the wire-passing channel, and the cable limiting devices 120 are used to vertically limit the cable.

[0060] It can be understood that the cable is clamped in the wire channel between the two track assemblies 300, the two tracks 340 can limit the left and right directions of the cable, and the cable limiting device 120 can limit the vertical direction of the cable, thereby reducing the risk of the cable moving vertically and detaching from between the two track assemblies 300.

[0061] like Figure 4 As shown, specifically, the cable limiting device 120 includes a column 121 arranged on the base frame 110, a lower roller 122 arranged on the column 121, and an upper roller 123 arranged on the column 121. The upper roller 123 and the lower roller 122 are arranged in parallel and at intervals, and one end of the upper roller 123 and the lower roller 122 are both facing left, and the other end is both facing right. The cable can be passed between the upper roller 123 and the lower roller 122. The upper roller 123 is used to limit the upper limit position of the cable, and the lower roller 122 is used to limit the lower limit position of the cable.

[0062] It should be noted that the upper roller 123 and the lower roller 122 are both rotatably arranged on the column 121, and both the upper roller 123 and the lower roller 122 can rotate around their own central axes. In this way, when the cable is transported between the upper roller 123 and the lower roller 122, when the cable contacts the upper roller 123 and / or the lower roller 122, the cable will drive the upper roller 123 and / or the lower roller 122 to rotate together, thereby reducing the friction of the cable during transportation.

[0063] Furthermore, the cable limiting device 120 also includes a first height adjustment mechanism 124 for adjusting the height of the lower roller 122, and a second height adjustment mechanism 125 for adjusting the height of the upper roller 123. Under the action of the first height adjustment mechanism 124 and the second height adjustment mechanism 125, the positions of the upper roller 123 and the lower roller 122 can be adjusted, thereby changing the upper limit position of the cable and the lower limit position of the cable.

[0064] like Figure 4 As shown, in some embodiments, a lifting ring 126 is provided on the base frame 110 , so that it is also convenient for operators to transport the entire base frame assembly 100 .

[0065] Specifically, there are four hanging rings 126 , which are respectively disposed at four corners of the base frame 110 .

[0066] like Figure 5 As shown, in some embodiments, the support assembly 200 includes a support leg 210 and a bearing device 220 disposed on the support leg 210. Figure 1 and Figure 5 The supporting foot 210 is detachably disposed on the base frame assembly 100 , and the carrying device 220 is used to carry two track assemblies 300 .

[0067] Specifically, the base frame assembly 100 (base frame 110) is provided with a first mounting hole 111, and the bottom of the support leg 210 is provided with a second mounting hole 211 corresponding to the first mounting hole 111. With the help of bolts and nuts, the support leg 210 can be fixed on the base frame assembly 100. At the same time, the bolts and nuts can also be removed, so that the entire support assembly 200 can be removed from the base frame assembly 100.

[0068] Combination Figure 1 and, Figure 7 and Figure 8 The carrying device 220 includes two carrying mechanisms 221, and the two carrying mechanisms 221 are arranged side by side and spaced apart, one on the left and one on the right. The two carrying mechanisms 221 respectively carry two track assemblies 300, and the two track assemblies 300 are respectively installed behind the two carrying mechanisms 221, and the two track assemblies 300 are also arranged side by side, one on the left and one on the right.

[0069] It should be noted that the track assembly 300 and the supporting mechanism 221 are detachably connected and can be disassembled, so that the track assembly 300 and the supporting mechanism 221 can be easily maintained separately.

[0070] Combination Figure 7 and Figure 8 In some embodiments, the distance between the two supporting mechanisms 221 is adjustable. Thus, the distance between the two track assemblies 300 can be adjusted to accommodate the transportation of cables of different diameters. The clamping force of the track assembly 300 on the cable can also be changed to ensure the reliability of cable transportation.

[0071] Combination Figure 5 and Figure 8 Specifically, the support assembly 200 also includes a guide shaft 223 connected to the support foot 210, the guide shaft 223 extends in the left-right direction, and two supporting mechanisms 221 are both sleeved on the guide shaft 223, one of the supporting mechanisms 221 is fixed relative to the guide shaft 223, and the other supporting mechanism 221 can move relative to the guide shaft 223 along the axial direction (left-right direction) of the guide shaft 223.

[0072] Furthermore, one of the supporting mechanisms 221 is defined as a fixed supporting mechanism 221a, and the other supporting mechanism 221 is defined as a movable supporting mechanism 221b. The fixed supporting mechanism 221a is fixed relative to the guide shaft 223, and the movable supporting mechanism 221b can move relative to the guide shaft 223 along the axial direction of the guide shaft.

[0073] Among them, the support assembly 200 also includes an adaptive adjustment mechanism 222, which includes a screw 2221 connected to the support foot 210 and arranged parallel to the guide shaft 223, a first nut 2222 sleeved on the screw 2221, a second nut 2223 sleeved on the screw 2221, and an elastic member 2224 connected to the first nut 2222 at one end, wherein the second nut 2223 and the first nut 2222 are arranged at intervals along the axial direction of the screw 2221, the fixed bearing mechanism 221a is fixedly connected to the second nut 2223, the elastic member 2224 is located on the side of the first nut 2222 close to the second nut 2223, and the movable bearing mechanism 221b is connected to the side of the elastic member 2224 away from the first nut 2222, and the elastic member 2224 can apply a force to the movable bearing mechanism 221b toward the fixed bearing mechanism 221a.

[0074] It is understandable that the two track assemblies 300 are respectively arranged on the two bearing mechanisms 221. When no cable passes between the two track assemblies 300, the distance between the two bearing mechanisms 221 can be changed by adjusting the relative positions of the first nut 2222 and the second nut 2223, thereby adjusting the distance between the two track assemblies 300. When the cable is clamped between the two track assemblies 300 and transported, if the cable passing between the two track assemblies 300 bends in the left-right direction, the force of the cable acting on the track assembly 300 will be transmitted to the elastic member 2224, causing the elastic member 2224 to contract, thereby causing the movable bearing mechanism 221b to move away from the fixed bearing mechanism 221a, thereby providing a buffer to prevent the risk of damage to the track assembly 300 and / or the cable due to excessive pressure between the cable and the track assembly 300.

[0075] The elastic member 2224 may be a spring, or a spring sheet or other elastic components.

[0076] Combination Fig.14 and Fig.15 In some embodiments, the movable bearing mechanism 221b is provided with a through hole 22133 for the screw rod 2221 to pass through, and a strain gauge 221332 is provided on the wall of the through hole 22133. The strain gauge 221332 is used to be electrically connected to an alarm device. The alarm device may be an alarm provided on the cable conveyor.

[0077] It is understandable that since the cable is not straight at every point, when the cable bends in the left-right direction, the cable will drive the entire movable bearing mechanism 221b to move in the left-right direction. If there is an assembly error, when the movable bearing mechanism 221b moves in the left-right direction, the screw 2221 may scrape the hole wall of the through hole 22133. In the present application, a strain gauge 221332 is provided on the hole wall of the through hole 22133. When an assembly error occurs, the screw 2221 will first collide with the strain gauge 221332, and the strain gauge 221332 will transmit a signal to the alarm device to alert the staff to perform maintenance, thereby increasing the service life of the cable conveyor.

[0078] Furthermore, an elastic corrugated sleeve 221331 is provided on the hole wall of the through hole 22133, and a plurality of strain gauges 221332 are provided, and the plurality of strain gauges 221332 are all provided on the side of the elastic corrugated sleeve 221331 away from the hole wall of the through hole 22133, and the plurality of strain gauges 221332 are provided at circumferential intervals along the through hole 22133, and the plurality of strain gauges 221332 are provided around the screw 2221.

[0079] It is understandable that the elastic corrugated sleeve 221331 is used to support the strain gauge 221332 and provide a buffer for the strain gauge 221332. If there is a problem that the screw 2221 scratches the strain gauge 221332, the elastic corrugated sleeve 221331 can be compressed to reduce the risk of the strain gauge 221332 being worn.

[0080] It should be noted that the hole wall of the through hole 22133 can be provided with an annular groove to install the elastic corrugated sleeve 221331, and the strain gauge 221332 can be pasted on the elastic corrugated sleeve 221331. The setting of the annular groove can increase the distance between the elastic corrugated sleeve 221331 and the screw rod 2221. However, it should be ensured that the side of the strain gauge 221332 close to the screw rod 2221 protrudes from the hole wall of the through hole 22133.

[0081] Combination Figure 8 and Fig. 9Furthermore, the bearing mechanism 221 includes a support plate 2211 and a support block 2213 arranged below the support plate 2211, and the support block 2213 is provided with a guide hole 22132 and a through hole 22133, wherein the guide hole 22132 and the through hole 22133 are arranged in parallel, and the axis of the guide hole 22132 and the axis of the through hole 22133 both extend in the left-right direction, the guide hole 22132 is used for the guide shaft 223 to pass through, and the through hole 22133 is used for the screw 2221 to pass through. The support block 2213 is a hollow structure. For the fixed bearing mechanism, the second nut 2223 is located inside the support block 2213 and is fixedly connected to the support block 2213. For the movable bearing mechanism 221b, the support block 2213 has two limiting walls 22131 spaced apart in the left-right direction. The first nut 2222 is located inside the support block 2213 and between the two limiting walls 22131. The first nut 2222 abuts against the limiting wall 22131 away from the fixed bearing mechanism 221a. One end of the elastic member 2224 abuts against the first nut 2222, and the other end abuts against the limiting wall 22131 close to the fixed bearing mechanism 221a. The elastic member 2224 is a spring, which is sleeved outside the screw rod 2221, and the screw rod 2221 can play a role in positioning the spring.

[0082] Combination Figure 5 and Fig. 9 Each bearing mechanism 221 is also provided with a driving unit 2212 at the bottom of a supporting plate 2211 , and the supporting plate 2211 is provided with an assembly hole 22111 penetrating the upper and lower sides thereof.

[0083] Specifically, the driving unit 2212 includes a driving motor 22121 and a transmission system 22122 drivingly connected to the driving motor 22121 . The transmission system 22122 is provided with a plug hole arranged opposite to the assembly hole 22111 .

[0084] More specifically, the transmission system 22122 includes a transmission rod 221221 with one end transmission-connected to the driving motor 22121 and a reduction box 221222 with the other end transmission-connected to the transmission rod 221221 , and the reduction box 221222 is provided with a socket.

[0085] Combination Figure 5 and Figure 6, wherein the transmission parts inside the reduction box 221222 include a first bevel gear 2212221 transmission connected to the other end of the transmission rod 221221, and a second bevel gear 2212222 meshing with the first bevel gear 2212221, wherein the first bevel gear 2212221 is coaxially arranged with the transmission rod 221221, the axis of the second bevel gear 2212222 is perpendicular to the axis of the first bevel gear 2212221, and the second bevel gear 2212222 is coaxial with and opposite to the socket of the reduction box 221222, and the second bevel gear 2212222 is provided with a connecting hole 22122221 arranged opposite to the socket.

[0086] It should be noted that the drive motor 22121 can be a high-power motor to provide greater driving force to increase the cable laying speed.

[0087] Combination Fig.10 and Fig.11 Each track assembly 300 includes a bracket 310, a driving shaft mechanism 320 arranged on the bracket 310, a driven shaft mechanism 330 arranged on the bracket 310 and spaced apart from the driving shaft mechanism 320 in the front-to-rear direction, and a track 340 wound around the driving shaft mechanism 320 and the driven shaft mechanism 330.

[0088] Specifically, the driving shaft mechanism 320 and the driven shaft mechanism 330 are parallel and arranged side by side, and the axial directions of the driving shaft mechanism 320 and the driven shaft mechanism 330 are parallel to the vertical direction. The two ends of the track 340 are respectively connected to the outside of the driving shaft mechanism 320 and the driven shaft mechanism 330. When the driving shaft mechanism 320 rotates, it can drive the track 340 to rotate.

[0089] It should be noted that, for the two track assemblies 300 , the tracks 340 on the two track assemblies 300 are arranged in parallel and at intervals in the left-right direction, and the cable can be passed between the tracks 340 of the two track assemblies 300 .

[0090] like Fig.11 and 12 As shown, the driving shaft mechanism 320 includes a driving shaft 321 rotatably connected to the bracket 310, and a driving gear 322 fixedly sleeved on the outside of the driving shaft 321. The driven shaft mechanism 330 includes a driven shaft 331 connected to the bracket 310, and a driven gear 332 rotatably sleeved on the outside of the driven shaft 331. The two ends of the crawler track 340 are respectively sleeved on the outside of the driving gear 322 and the driven gear 332.

[0091] For each set of corresponding supporting mechanisms 221 and track assemblies 300 , the driving shaft mechanism 320 on the track assemblies 300 is passed through the assembly hole 22111 of the supporting mechanism 221 and is transmission-connected to the driving unit 2212 of the supporting mechanism 221 .

[0092] Specifically, the driving shaft 321 passes through the assembly hole 22111 of the support plate 2211, is inserted into the insertion hole of the reduction box 221222, and is inserted into the connecting hole 22122221 of the second bevel gear 2212222, wherein the hole wall of the connecting hole 22122221 and the driving shaft 321 can be connected by a key. Specifically, the hole wall of the connecting hole 22122221 can be provided with a key, and the outer side wall of the driving shaft 321 is provided with a keyway for the key to pass through. After the driving shaft 321 passes through the connecting hole 22122221, the key can be inserted into the keyway, so that the driving shaft 321 and the second bevel gear 2212222 can be driven.

[0093] It can be understood that when the driving motor 22121 is working, the transmission rod 221221 can drive the first bevel gear 2212221 and the second bevel gear 2212222 to rotate, thereby driving the driving shaft mechanism 320 to rotate, so that the crawler track 340 works.

[0094] It can also be understood that in the process of installing the track assembly 300 to the supporting mechanism 221, the kinetic energy transmission between the drive unit 2212 and the driving shaft mechanism 320 can be realized after the driving shaft mechanism 320 is inserted into the assembly hole 22111, and the installation is very convenient. In addition, the track assembly 300 and the supporting mechanism 221 can be fixed by bolting.

[0095] like Fig.11 and Fig.12 As shown, in some embodiments, the track assembly 300 further includes a tension adjustment mechanism 350 disposed on the bracket 310 and used for adjusting the distance between the driving shaft mechanism 320 and the driven shaft mechanism 330 .

[0096] It is understandable that as the cable conveyor runs, the track 340 may become loose. By adjusting the distance between the driving shaft mechanism 320 and the driven shaft mechanism 330 so that the distance between the driving shaft mechanism 320 and the driven shaft mechanism 330 becomes larger, the track 340 can be made tighter, thereby improving the stability of the transmission cable.

[0097] Combination Fig.12 and Fig.13Specifically, the tension adjustment mechanism 350 includes an adjustment unit 351 and an abutment block 352 connected to the adjustment unit 351. The abutment block 352 abuts against the driven shaft mechanism 330. The adjustment unit 351 can operably drive the abutment block 352 to move toward or away from the driving shaft mechanism 320. When the abutment block 352 moves away from the driving shaft mechanism 320, the abutment block 352 pushes the driven shaft mechanism 330 away from the driving shaft mechanism 320, thereby tightening the track 340. When the abutment block 352 moves toward the driving shaft mechanism 320, the track 340 will become loose.

[0098] Among them, the side of the abutment block 352 close to the driven shaft mechanism 330 is an arc-shaped surface, and the arc-shaped surface is adapted to the side of the driven shaft 331. In this way, the contact area between the abutment block and the driven shaft 331 can be increased, the stability between the abutment block and the driven shaft 331 can be improved, and the risk of misalignment between the abutment block and the driven shaft 331 can be reduced.

[0099] Combination Fig.12 and Fig.13 In some embodiments, the adjusting unit 351 includes an adjusting rod 3511, a third bevel gear 3512 connected to one end of the adjusting rod 3511, a fourth bevel gear 3513 meshing with the third bevel gear 3512, a threaded sleeve 3514 transmission-connected to the fourth bevel gear 3513, and an adjusting screw 3515 inserted into the threaded sleeve 3514, and the adjusting screw 3515 is connected to the abutment block 352.

[0100] Specifically, the axial direction of the adjusting screw 3515 is parallel to the spacing direction of the driving shaft mechanism 320 and the driven shaft mechanism 330; the threaded sleeve 3514 is sleeved outside the adjusting screw 3515 and supported by the bracket 310, the threaded sleeve 3514 is rotatably arranged on the bracket 310 through a bearing, the threaded sleeve 3514 can rotate around the axis of the threaded sleeve 3514 relative to the bracket 310, the fourth bevel gear 3513 is sleeved outside the threaded sleeve 3514, and the fourth bevel gear 3513 and the threaded sleeve 3514 are connected by a key, the fourth bevel gear 3513 and the threaded sleeve 3514 can rotate synchronously, and the third bevel gear 3512 and the fourth bevel gear 35 13 is meshed, the axis of the third bevel gear 3512 is perpendicular to the axis of the fourth bevel gear 3513, the adjusting rod 3511 is fixedly connected to the fourth bevel gear 3513, and the adjusting rod 3511 is coaxially arranged with the fourth bevel gear 3513, the adjusting rod 3511 is rotatably arranged on the bracket 310 through a bearing, the adjusting rod 3511 can be rotated, thereby driving the third bevel gear 3512 and the fourth bevel gear 3513 to rotate, thereby causing the threaded sleeve 3514 to rotate, and then driving the adjusting screw 3515 to move along the spacing direction of the driving shaft mechanism 320 and the driven shaft mechanism 330, thereby adjusting the position of the abutment block 352.

[0101] Furthermore, the bracket 310 is provided with a guide groove 311 , the length direction of the guide groove 311 is parallel to the spacing direction of the driving shaft mechanism 320 and the driven shaft mechanism 330 , the end of the driven shaft mechanism 330 is inserted into the guide groove 311 , and the guide groove 311 guides the movement of the driven shaft mechanism 330 .

[0102] like Fig.11 As shown, in some embodiments, the bracket 310 is further provided with a handle 360 ​​to facilitate workers to carry the track assembly 300 .

[0103] The present invention also relates to an assembly method of a cable conveyor, which is applied to the cable conveyor of the above embodiment. The assembly method of the cable conveyor comprises:

[0104] The chassis assembly 100 is preassembled into an independent module; the support assembly 200 is preassembled into an independent module; and the two track assemblies 300 are preassembled into independent modules respectively;

[0105] The underframe assembly 100, the support assembly 200 and the track assembly 300 are transported to the construction site respectively;

[0106] The support assembly 200 is assembled onto the underframe assembly 100 , and then the two track assemblies 300 are assembled onto the support assembly 200 respectively.

[0107] In the assembly method of the cable conveyor of the present invention, the chassis assembly 100, the support assembly 200 and the track assembly 300 are modularly designed. During transportation, the pre-assembled chassis assembly 100, the support assembly 200 and the track assembly 300 can be transported separately and then assembled on site. For narrow areas, such as wellheads, the entire cable conveyor may not be accessible, and the purpose of transportation can be achieved by transporting the chassis assembly 100, the support assembly 200 and the track assembly 300 of the cable conveyor separately, thereby improving the adaptability and flexibility of the equipment in complex terrain and narrow space. In addition, the track assembly 300, the support assembly 200 and the chassis assembly 100 can be disassembled, making the maintenance and upgrading of the equipment easier.
