Description

Technical Field

[0001] The invention relates to the field of cable laying construction, and in particular to underground cable well laying construction equipment. Background Art

[0002] The Chinese patent with publication number CN111029972A (a fixing device for turning underground cables) discloses that during the cable laying process, there will be a turning situation. When the cable is pulled, the turning position of the cable will cause wear between the cable and the wall, which reduces the service life of the cable. It also discloses a technical solution of passing the cable through a guide wheel so that the cable and the guide wheel cooperate, and pulling the cable for laying. During the cable pulling process, the guide wheel rolls accordingly, which can prevent friction between the cable and the wall, reduce labor intensity, and prevent cable wear and increase service life;

[0003] However, the problems with this patent (a fixing device for turning underground cables) are:

[0004] 1. The cable is not guided in an arc shape, and the cable still has a large deformation at the corner;

[0005] 2. When the cable is actually dragged and laid, a cable mesh is used to connect the cable, and a traction rope is used to connect the cable mesh, and then a cable reel is used to reel in the traction rope to achieve the dragging and laying of the cable. Since the cable mesh is usually fixed to the surface of the cable with steel wire, the guide wheel of the patent (a fixing device for turning underground cables) will be damaged by the steel wire when guiding the cable mesh, and the damaged guide wheel will affect the smooth guidance of the cable and even scratch the cable skin. Summary of the invention

[0006] In order to overcome the shortcomings of the prior art that the cable cannot be guided in an arc shape at the corner and the steel wire used to fix the cable mesh will damage the guide wheel, the present invention provides an underground cable well laying construction equipment.

[0007] The technical implementation scheme of the present invention is: an underground cable well laying construction equipment, including a connecting member and a guide wheel, the connecting member is connected to the guide wheel; there are three guide wheels on the connecting member, and the wheels of all guide wheels are arranged in an arc shape as a whole; it also includes a first pushing member and a protective wheel; two first pushing members are installed on the connecting member, the first pushing members are arranged between two adjacent guide wheels, and each telescopic part of the first pushing member is fixedly connected to a protective wheel.

[0008] Optionally, the size of the protection wheel is larger than the size of the guide wheel.

[0009] Optionally, the guide wheel is adapted to the size of the cable being pulled.

[0010] Optionally, the guide wheel located in the middle is connected to the connecting member through a second pushing member, the fixed portion of the second pushing member is fixed on the connecting member, and the telescopic portion of the second pushing member is fixedly connected to the guide wheel.

[0011] Optionally, the guide wheels on both sides are connected to the connecting member via a third pushing member, a fixed portion of the third pushing member is fixed on the connecting member, and a telescopic portion of the third pushing member is fixedly connected to the guide wheels.

[0013] Optionally, an anti-slip assembly is also installed on each of the two protection wheels.

[0014] Optionally, it also includes a fixing ring and an insertion rod; two fixing rings are fixedly connected to the connecting piece, and two insertion rods are detachably plugged into the connecting piece.

[0016] Optionally, the surface of the wheel of the protection wheel is provided with a wear-resistant layer.

[0017] The invention has the following advantages: the invention overcomes the problem in the prior art that the cable cannot be guided in an arc shape and the steel wire used for fixing the cable mesh sleeve may damage the guide wheel.

[0018] When the present invention is working, the cable is guided by three guide wheels which are arranged in an arc shape as a whole, so that the cable can be prevented from being excessively bent, and damage caused by friction between the cable and the hole can be prevented, which leads to a reduction in the service life of the cable.

[0019] Using larger protective wheels to guide the traction rope and cable mesh with steel wire, two guided objects that are inconsistent with the cable size, not only allows the guide wheel that matches the cable size to subsequently guide the cable stably, but also prevents the steel wire from damaging the guide wheel, thereby ensuring safe and stable cable guidance by the guide wheel.

DETAILED DESCRIPTION

[0026] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] Example 1

[0028] An underground cable well laying construction equipment, such as Figure 1-2 As shown, it includes a connecting member 1 and a guide wheel 2, the connecting member 1 is connected to the guide wheel 2, and the cable is guided by the guide wheel 2;

[0029] There are three guide wheels 2 on the connecting member 1, and the wheels of all guide wheels 2 are arranged in an arc shape as a whole;

[0030] It also includes a first pushing member 3 and a protective wheel 4; two first pushing members 3 are installed on the connecting member 1, and the first pushing members 3 are arranged between two adjacent guide wheels 2. Each telescopic part of the first pushing member 3 is fixedly connected to a protective wheel 4. In the initial stage of cable guiding, the traction rope and the cable mesh are guided by the protective wheel 4.

[0031] The size of the protection wheel 4 is larger than that of the guide wheel 2 .

[0032] The guide wheel 2 is adapted to the size of the cable being pulled to prevent the cable from moving up and down on the guide wheel 2 during guidance, thereby preventing the cable from being unstable in guidance.

[0033] In order to overcome the problem in the prior art that the cable cannot be guided in an arc shape and the steel wire used to fix the cable mesh will damage the guide wheel, when the present invention is working, Figure 1 As shown, the connector 1 is installed at the right-angle corner 200 of the underground cable well, and the cable is guided to the state shown by the cable 100 bent into an arc shape by three guide wheels 2 arranged in an overall arc shape. This can prevent the cable from being excessively bent, and can also prevent the cable from being damaged by friction with the hole 200a, resulting in a reduction in its service life.

[0034] It should be noted that the guide wheel 2 is adapted to the size of the guided cable to prevent the cable from moving up and down on the guide wheel 2 during guidance, thereby maintaining stable cable guidance.

[0035] Furthermore, in the early stage of cable guiding, there are two guided objects, namely, traction rope and cable mesh with steel wire, which are inconsistent with the size of the cable. At this time, the size of the guide wheel 2 may not be able to guide the traction rope and the cable mesh with steel wire. Therefore, in the early stage of cable guiding, the two first pushers 3 are first controlled to push the two protection wheels 4 to move forward, so that the two protection wheels 4 are in contact with the traction rope and the cable mesh with steel wire and guide them. Because the size of the protection wheel 4 is larger, the traction rope and the cable mesh with steel wire can be guided and guided, thereby avoiding the guide wheel 2 from guiding the traction rope and the cable mesh with steel wire, and guiding the cable mesh with steel wire by the protection wheel 4 can also avoid the steel wire from damaging the guide wheel 2. The present invention uses the larger protection wheel 4 to guide the two guided objects, namely, the traction rope and the cable mesh with steel wire, which are inconsistent with the size of the cable. Not only can the guide wheel 2 adapted to the size of the cable be able to stably guide the cable later, but also the steel wire can be avoided from damaging the guide wheel 2, thereby achieving safe and stable guarantee of the cable guidance by the guide wheel 2.

[0036] It should be noted that after the protection wheel 4 completes the guidance of the traction rope and the cable mesh with steel wire, the first pusher 3 is controlled to push the two protection wheels 4 to slowly retreat, so that the cable can contact the guide wheel 2 again, and then the cable can be guided by the guide wheel 2.

[0037] Example 2

[0038] On the basis of Example 1, Figure 2 As shown, the guide wheel 2 located in the middle is connected to the connecting member 1 through the second pushing member 2a, the fixed part of the second pushing member 2a is fixed on the connecting member 1, and the telescopic part of the second pushing member 2a is fixedly connected to the guide wheel 2.

[0039] The guide wheels 2 located on both sides are connected to the connecting member 1 via the third pushing member 2 b , the fixed portion of the third pushing member 2 b is fixed on the connecting member 1 , and the telescopic portion of the third pushing member 2 b is fixedly connected to the guide wheel 2 .

[0040] Furthermore, if Figure 1 As shown, because the position of the hole 200a is set differently, the curvature of the arc guided by the cable will also be different. To overcome this problem, the second pushing member 2a can be controlled to push the middle guide wheel 2 forward or backward to adjust the overall curvature of the arc of the three guide wheels 2, so as to achieve the guiding work of arc cables with different curvatures.

[0041] Furthermore, if Figure 1 As shown, there are multiple cables that need to be guided at the same horizontal height, and the connecting member 1 is not convenient to disassemble and install after being fixed. Therefore, in order to facilitate the orderly installation of multiple cables, the second pushing member 2a can be controlled to push the middle guide wheel 2 to move forward or backward, and the two third pushing members 2b can push the guide wheels 2 on both sides to move forward or backward to achieve the guiding work of the cables located at different positions, avoiding the need for repeated installation and disassembly to achieve a better guiding effect.

[0042] Example 3

[0043] On the basis of Examples 1 and 2, Figure 1-5 As shown, it also includes an anti-dropping component consisting of a connecting plate 101, a driving motor 102, a baffle 103 and a clamping block 104; each guide wheel 2 is fixedly connected to a connecting plate 101 at the upper and lower parts, and a driving motor 102 is installed in the connecting plate 101 located at the bottom, and a baffle 103 is fixedly connected to the rotating part of the driving motor 102, and the baffle 103 is driven by the driving motor 102 to rotate, so that the baffle 103 blocks the guide wheel 2 to prevent the cable from falling off, and a clamping block 104 is fixedly connected to the baffle 103, and the clamping block 104 slides in the slot of the connecting plate 101 located at the top.

[0044] An anti-drop assembly (not shown in the figure) is also installed on each of the two protection wheels 4 to ensure that the traction rope and the cable mesh with steel wire will not fall off when the protection wheel 4 guides the traction rope and the cable mesh with steel wire.

[0045] Furthermore, considering that when the guide wheel 2 guides the cable, there may be problems such as power outages, broken traction ropes, or detachment of various connections during the cable guiding process, the cable will fall off the guide wheel 2 at this time. To address this problem, when the guide wheel 2 guides the cable, the drive motor 102 is controlled to drive the baffle 103 and the block 104 to rotate, so that the block 104 is inserted into the groove of the upper connecting plate 101, and the baffle 103 blocks the guide wheel 2 to prevent the cable from falling off, thereby realizing the use of the baffle 103 to protect the cable from falling off, and avoiding the trouble and danger of reinstalling it after it falls off.

[0046] It should be noted that, because the cable is in a straightened state when being pulled, and the guide wheel 2 has a sufficient depth, the baffle 103 will not rub against the cable during the normal cable guiding process.

[0047] Example 4

[0048] On the basis of Examples 1, 2, and 3, Figure 1-3 As shown, it also includes a fixing ring 201 and an insertion rod 202; two fixing rings 201 are fixedly connected to the connecting member 1, and two insertion rods 202 are detachably inserted on the connecting member 1. The insertion rods 202 are fixed on the ground, and the fixing rings 201 are fixed to the insertion rods 202 using nuts to fix the connecting member 1.

[0049] When the connector 1 needs to be fixed, the fixing ring 201 and the plug rod 202 can be selected to fix it in the underground cable well, or other methods can be used; when the fixing ring 201 and the plug rod 202 are used, the plug rod 202 is fixed in a suitable position in the cable well in advance, and then the connector 1 and the fixing ring 201 on the connector 1 are plugged into the plug rod 202, and the fixing ring 201 is fixed to the plug rod 202 with a nut, so as to achieve the fixing work of the connector 1, such as Figure 1 , 3 As shown, when multiple cables need to be installed simultaneously in the vertical direction, multiple connectors 1 can be installed on the insertion rod 202 to achieve synchronous installation of the multiple cables.

[0050] The first pusher 3, the second pusher 2a and the third pusher 2b are electric push rods.

[0051] The surface of the wheel of the protection wheel 4 is provided with a wear-resistant layer.
