Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel boring equipment, in particular to a rear-end matching cable trailer, a cable storage container and a tunnel boring machine. Background Art

[0002] The tunnel boring machine is equipped with many electrically driven devices. During the tunneling process, the supporting cables also need to be extended forward. At present, tunnel boring machines usually pre-store cables to compensate for the extension of cables during the tunneling process. There are two types of cable storage devices: cable reels or cable boxes. Cable boxes are widely used due to their simple structure and low cost.

[0003] The cable box is generally installed on the rear supporting trailer. In order to reduce the space occupied by the cable box on the trailer, the applicant's Chinese utility model patent with the authorization announcement number CN214227791U provides a hanging type cable box, the trailer is provided with a floating hanging structure for hanging the cable box, specifically the hanging structure is a floating zipper, the cable box is provided with an ear seat for cooperating with the floating zipper, and the floating zipper and the ear seat are connected by bolts and nuts. This hanging type cable box does not occupy the space at the bottom of the trailer, and it is convenient for the staff to pass through the trailer (under the cable box).

[0004] In actual construction, when the cables stored in the cable box are used up, the machine needs to be stopped to disassemble the cable box, lower the cable box to the bottom, and then add cables to the cable box. When disassembling the cable box, the bolts and nuts between the floating zipper and the ear seat need to be removed manually using tools, which is inconvenient and inefficient. In addition, the cable box floats during the excavation process and has poor stability. Utility Model Content

DETAILED DESCRIPTION

[0053] Box-type (including covered and uncovered) cable storage containers are currently widely used in the rear-end supporting system of tunnel boring machines due to their low cost. They are generally installed on the rear-end supporting cable trailer (hereinafter referred to as the trailer) and move with the trailer. The hoisting cable box developed by the applicant in the early stage has the advantage of occupying a small space and has been successfully applied to various types of tunnel boring machines. However, the cables stored in the cable box at one time are limited. Due to the size of the trailer, the cable box cannot be infinitely large. Therefore, in actual application, there is the problem of replenishing cables in the cable box.

[0054] At present, in actual operation, the cable box needs to be removed from the trailer, and generally the bolts, nuts and other structures are removed from the ear plate of the cable box manually using tools, but this method is inconvenient to operate and has low efficiency.

[0055] In order to solve the above problems, the basic technical concept of the utility model is to improve the existing trailer and cable box (container), retain the original hanging mechanism for hanging and supporting the cable box on the trailer, and set the hanging mechanism to include a supporting member that can automatically cooperate with and separate from the cable box support. When disassembly is required, the supporting member and the cable storage container are automatically separated, and there is no need for manual use of complex disassembly and assembly tools, which is highly efficient.

[0056] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0057] The specific embodiment of the rear-mounted cable trailer provided by the utility model is as follows:

[0058] The trailer 1 provided in this embodiment is as follows Figure 1-Figure 4 As shown, it includes a frame 101, on which a hanging mechanism 3 for hanging a cable storage container 2 and a lifting mechanism 4 for lifting and lowering the cable storage container 2 are provided. The cable storage container 2 is a box-type structure, including an outer wall, which includes side walls and a bottom wall on all sides, and the side walls and the bottom wall enclose a cavity for placing cables.

[0059] Regarding the hanging mechanism 3, in order to satisfy its hanging support for the cable storage container 2, the hanging mechanism 3 should at least include two hanging units arranged opposite to each other, and the two hanging units respectively cooperate with the two side walls of the cable storage container 2 that are separated from each other to play a supporting role for the cable storage container 2. In this embodiment, the hanging mechanism 3 includes a total of four hanging units, and the four hanging units are grouped in pairs, and the two hanging units in each group of hanging units are arranged at intervals and are used to cooperate with the same side wall of the cable storage container to play a supporting role together, so that a support arm with a certain span can be formed, which is more suitable for large cable storage containers.

[0060] Regarding the lifting mechanism 4, in order to enable it to drive the cable storage container 2 to be lifted and lowered, it should at least include two lifting units arranged opposite to each other, and the two lifting units are respectively used to cooperate with the two side walls of the cable storage container that are separated from each other. In this embodiment, the lifting mechanism 4 includes a total of four lifting units, and the four lifting units are grouped in pairs, and the two lifting units in each group of lifting units are arranged at intervals and are used to cooperate with the same side wall of the cable storage container to jointly play a hanging role.

[0061] It should be noted that the specific installation method and quantity of each hanging unit and lifting unit can be flexibly set according to the structure of the frame 101 and the cable storage container 2, and no specific limitation is made here.

[0062] As an automatic hanging mechanism 3, it includes a movable support member 301 and a support driving device that drives the support member 301 to move. In the movable stroke of the support member 301, there is a hanging support position that cooperates with the cable storage container 2 to play a hanging support role, such as Figure 3 and Figure 4 As shown, there is also an avoidance position for avoiding the cable storage container 2 to meet the up and down movement of the cable storage container, such as Figure 1 and Figure 2 shown.

[0063] Specifically, the support member 301 in this embodiment is a swing-type swing support member, such as Figure 5 and Figure 6As shown, the support member 301 has a certain support member hinge shaft 305, the hinge axis of the support member hinge shaft 305 extends in the vertical direction, and the support driving device driving the support member 301 to swing is a swing cylinder 302. At the same time, the cable storage container 2 should be provided with a hanging member 201 for cooperating with the support member 301. When the support member 301 rotates to the bottom of the hanging member 201, it can support and cooperate with the hanging member 201 to play a supporting role. For the cable storage container 2, in order to meet the support member 301 to move to the position where it supports and cooperates with the hanging member 201, the cable storage container 2 should have an opening channel that meets the support member 201 to enter (support) and move out (separate).

[0064] More specifically, the support member 301 can be installed on the vehicle frame 101 through a support member mounting bracket, such as Figure 5 , Figure 6 , Fig.11 , Fig.12 As shown, the support member installation support includes a horizontal support 303 and a vertical support 304. The specific forms of the horizontal support 303 and the vertical support 304 are not limited, and they can be processed using scraps at the production site. A support member hinge seat 307 is installed on the horizontal support 303, and the support member 301 is installed on the support member hinge seat 307 through a support member hinge shaft 305. In this way, through the installation structure of the support member installation support, the hinged parts of the support member can be assembled first and then installed on the frame 101 as a whole, and the installation efficiency is high. In other embodiments, the support member can also be directly hinged and installed on the frame through the hinge shaft. In addition, depending on the structure of the frame and the installation space, the support member installation support can also be only a horizontal support 303 or a vertical support 304, which can be installed on the frame by bolts or welding.

[0065] The two ends of the swing cylinder 302 are respectively hinged to the frame 101 and the support member 301. Figure 5 , Figure 6 , Fig.13 , Fig.14 As shown, a first cylinder articulated shaft 306 is provided on the support member 301, and the telescopic rod end of the swing cylinder 302 is articulated with the support member through the first cylinder articulated shaft 306. A swing cylinder mounting seat 308 is installed on the frame 101, and a second cylinder articulated shaft 3081 is provided on the swing cylinder mounting seat, and the telescopic cylinder end of the swing cylinder 302 is articulated with the swing cylinder mounting seat 308 through the second cylinder articulated shaft 3081.

[0066] Driven by the swing cylinder 302, the support member 301 can swing to the bottom of the hanging member 201 on the side wall of the cable storage container 2 to play a supporting role. At the same time, it can also leave from under the hanging member 201 of the cable storage container 2 to release the supporting role and avoid the cable storage container 2 from moving up and down.

[0067] In this embodiment, when the cable storage container 2 needs to be disassembled and installed, since the support member 301 can be actively swung and switched between the supporting position and the avoiding position, there is no need for manual operation with tools. Only the swing cylinder 302 needs to be controlled, which is highly efficient.

[0068] In order to ensure the stability of the support, the support member 301 in this embodiment is selected as a block-shaped support member with a horizontal upper surface. Correspondingly, the hanging member 201 on the cable storage container 2 is also a block-shaped structure with a horizontal lower surface. When the two are matched, the upper surface of the support member 301 and the lower surface of the hanging member 201 support and match with each other, and have good stability. At this time, the upper surface of the support member 301 forms a hanging support surface, and the lower surface of the hanging member 201 forms a lower support surface.

[0069] In other embodiments, the support member 301 may also be a cylindrical structure. In this case, the hanging member 201 may be selected to be a fan-shaped ring member with a curved surface. The support member 301 cooperates with the curved surface and can also play a supporting role.

[0070] In order to improve the stability of the cable storage container 2 and prevent the support member 301 from swinging excessively, the cable storage container 2 is also provided with a side limiter 202 for cooperating with the support member 301 to limit the relative position of the support member 301 and the cable storage container 2. This limits the position of the cable storage container 2 relative to the front and rear directions of the trailer and prevents the support member 301 from swinging excessively. At the same time, under the action of the swing cylinder, the support member can be close to the side limiter 202. At this time, the cable storage container 2 is stable in both the front and rear directions (the trailer's forward direction) and the left and right directions (the trailer's lateral direction). Figure 5 and Figure 8 As shown, this embodiment provides a side limiter 202 integrated on the hanging member 201. Specifically, the cross section of the hanging member 201 is an inverted L-shaped structure, and the side limiter 202 is a plate-shaped structure welded or bolted or integrally machined on the hanging member 201. At this time, the opening on the other side opposite to the side limiter 202 is an opening channel for the support member 301 to enter and move out. Of course, in other embodiments, the side limiter can also be directly arranged on the side wall of the cable storage container 2, and it can play a role in cooperating with the support member to stop.

[0071] In other embodiments, the support driving device for driving the support member 301 to swing may also be other forms of telescopic devices, such as a cylinder or an electric cylinder, etc. Of course, a rotary power device may also be selected, such as a stepper motor, and the power output shaft of the stepper motor is connected to the support member articulated shaft by transmission.

[0072] It should be noted that, for tunnels with a small slope, in actual application, the cable storage container 2 is subjected to a small force in the front-to-back direction, and the cable storage container 2 is relatively stable. In this case, the side limiter can also be omitted. In order to prevent the support member 301 from rotating excessively, the support drive device can be designed at this time, such as selecting a stepper motor, and the angle of each rotation is fixed. In the case of no side limiter, the space below the hanging member 201 is relatively open, and the space below the hanging member 201 can be regarded as an open channel for the support member 301 to enter and move out.

[0073] In other embodiments, the support member 301 may also be a direct-acting support member, and using a cylinder to drive the support member 301 to move forward in a straight line to the bottom of the hanging member 201, and to drive the support member to move away from the bottom of the hanging member, is also a feasible solution. In this case, the support member 301 can be slidably assembled on the support. In addition, for this direct-acting support member, the hanging member 201 can also be selected as a cylindrical structure, such as a cylinder, and the support member 301 can be inserted into the cylinder to achieve the supporting function. In this case, the opening of the cylinder can be regarded as an opening channel for the support member 301 to enter and move out.

[0074] The lifting mechanism 4 includes a lifting drive device and a lifting connector that can move up and down. The lifting connector is used to connect the cable storage container 2. The outer wall of the cable storage container 2 is provided with a lifting component that is used to connect with the lifting connector. The lifting mechanism 4 drives the cable storage container 2 to rise, and the cable storage container 2 should be able to cooperate with the hanging mechanism 3 to hang. Figure 5 For example, the ascending stroke of the lifting mechanism 4 should be sufficient for the hanging member 201 to move to the top of the supporting member 301.

[0075] This embodiment provides a method of using a winch as a lifting mechanism. Regarding the winch, those skilled in the art know that it should include a basic rotating power part (motor, hydraulic motor, etc.), a drum, a sling 401 (chain or rope), and a hook, etc., and the hook is installed on the sling 401. At this time, the rotating power part configured in the winch is equivalent to a lifting drive device, and the hook is equivalent to a lifting connection part.

[0076] In order to enable the winch to lift the cable storage container 2 to a higher position, a lifting mechanism mounting frame 6 is also installed on the vehicle frame 101 in this embodiment. Figure 1-4 , Figure 7 and Fig.10As shown, the hoisting mechanism mounting frame 6 extends upward as a whole, and includes a vertical bracket 601 and a horizontal bracket 602, and the vertical bracket 601 and the horizontal bracket 602 can be connected as a whole by welding or bolts. The hoist is installed on the horizontal bracket 602. In this way, the installation position of the hoist can be raised, so that it is also convenient to lift the cable storage container 2 to a higher position. In other embodiments, depending on the different positions where the cable storage container 2 needs to be lifted, if the hoist is installed on the frame 101 to meet the requirements of lifting the cable storage container 2 to a position where it can be hung on the hanging mechanism 3, the hoisting mechanism mounting frame 6 may not be provided.

[0077] In order to meet the connection between the cable storage container 2 and the hook, as Figure 8 As shown, a lifting lug 204 is provided on one side of the outer wall of the cable storage container 2, and a shoulder pole structure is provided on the other side of the outer wall. The shoulder pole structure includes a shoulder pole shaft 203 provided on the cable storage container 2 and a shoulder pole beam 205 movably sleeved on the shoulder pole shaft. The structure of the shoulder pole beam 205 is as shown in FIG. Fig. 9 As shown, a shoulder pole center hole 2051 is provided at its center position, through which the shoulder pole center hole 2051 can be mounted on the shoulder pole beam 205, and the center line of the shoulder pole center hole 2051 is the rotation center of the shoulder pole beam 205. Lifting parts for connecting with the lifting connector of the lifting mechanism are provided on both sides of the rotation center. Specifically, when the lifting mechanism is a winch, the lifting part can be formed by a lifting shaft 2052 provided on both sides of the shoulder pole beam 205, and the hook can hook the lifting shaft 2052 to achieve its connection with the shoulder pole beam 205. Of course, the lifting part can also be a lifting lug installed on both sides of the shoulder pole beam. Such arrangement of the shoulder pole beam 205 can balance the forces on the connection points of different lifting mechanisms. For the winch, this can balance the forces on the two lifting points of the winch.

[0078] Above-mentioned shoulder pole beam 205 and lifting lug 204 can be installed on the side wall, also can be installed on the bottom wall, and those skilled in the art can flexibly arrange as required.In fact, in order to connect the hook of hoist, can all adopt lifting lug or arrange two shoulder pole beams.

[0079] In other embodiments, the lifting mechanism may also select other structures besides the winch. For example, a direct-acting mechanism such as an oil cylinder or an electric cylinder may be selected. Taking the oil cylinder as an example, the cylinder barrel may be fixed on the trailer, the cylinder rod may be connected with the cable storage container 2, and the extension of the cylinder rod may directly push the cable storage container 2 up and down. In this case, the cylinder rod may be regarded as a lifting connection part, and the oil cylinder itself may be regarded as a lifting drive device.

[0080] When the cable storage container 2 needs to be disassembled, the lifting mechanism can first lift the cable storage container 2 and hold it to a certain height, and after the support is removed, the cable storage container 2 can be automatically driven down, thereby improving efficiency. At the same time, under normal circumstances, the lifting mechanism can also be connected to the cable storage container 2 and cooperate with the hanging mechanism to play a double insurance role.

[0081] In other embodiments, the trailer does not have its own lifting mechanism 4, and the on-site staff installs the lifting mechanism as needed or directly uses the monorail material transportation system in the tunnel to lift the cable storage container 2. However, the configuration of the lifting mechanism has higher efficiency.

[0082] In order to prevent the cable storage container from rising too high and moving upward, and to determine whether the cable storage container has risen to the hanging position. In this embodiment, the frame 101 is also provided with an upper limit plate 5, such as Figure 1-4 and Fig.15 As shown, the upper limit plate 5 is connected to the upper limit plate mounting seat 501 and is mounted on the vehicle frame 101 by screws 502. The screws 502 are used for later disassembly. In other embodiments, welding is also possible. When the cable storage container 2 rises to just touch the upper limit plate 5, it means that the cable storage container 2 is in place. Under the action of the upper limit plate 5, the cable storage container 2 can be restricted to a suitable position and provide a reference for the movement timing of the support member 301.
