Description

Technical Field

[0001] The utility model relates to the technical field of slope construction, in particular to an auxiliary device for a slope inclinometer. Background Art

[0002] Inclinometers are often used to detect lateral displacement of soil in landslide areas and deep hole excavation. They are also used to detect deformation of structures such as dams, or to detect the bottom settlement of large buildings by horizontally pre-buried inclinometer tubes. The basic configuration of the inclinometer includes inclinometer casing, inclinometer probe, control cable and inclinometer reading instrument. During the use of the inclinometer, the inclinometer probe needs to be inserted into the inclinometer tube buried in the stratum through the control cable, and then the cable is pulled upward. According to the marks on the cable, the inclination of the inclinometer tube axis relative to the reference axis is measured every certain distance until the tube mouth.

[0003] During the actual construction process, unstable soil layers will deform and settle, and the inclinometer tube will deform along with the deformation of the soil. When a transverse crack or a sudden change in transverse displacement occurs somewhere in the inclinometer tube, especially at the coupling position, a guide wheel on the inclinometer probe may get stuck, and the inclinometer probe cannot slide normally. At this time, if the inclinometer is pulled hard, the inclinometer cable may break. Utility Model Content

[0004] The utility model aims to provide an auxiliary device for a slope inclinometer to solve the problem that when the guide wheel of the slope inclinometer is stuck during construction, the inclinometer is directly pulled up, which easily leads to the breakage of the inclinometer cable.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An auxiliary device for a slope inclinometer, comprising a clamping member and a traction rope connected to the clamping member, wherein the clamping member comprises a first rotating shaft and a first clamping sub-member and a second clamping sub-member both rotatably connected to the first rotating shaft and in a square frame shape;

[0007] The first clamping sub-component includes a first connecting side rotatably connected to the first rotating shaft and a first clamping side opposite to the first connecting side. The first clamping side is axially provided with an opening and closing rod, and the opening and closing rod includes a rotating end rotatably connected to the first clamping side and a limiting end detachably connected to the first clamping side.

[0008] During the construction of the slope, when operating the inclinometer, due to the deformation and settlement of the unstable soil layer, the inclinometer tube will deform with the deformation of the soil mass. When there is a horizontal crack or a sudden change in horizontal displacement at a certain part of the inclinometer tube, especially at the coupling position, one of the guide wheels on the inclinometer probe will be stuck, and the inclinometer probe cannot slide normally. Directly pulling up the inclinometer easily causes the inclinometer cable to break. Based on the above problems, the present utility model provides an auxiliary device for a slope inclinometer. By adopting a clamping member with a square frame structure and arranging an opening and closing rod on the sub-member on one side of the clamping member, when the clamping member is lowered to the position where the inclinometer is stuck by using a traction rope, when the opening and closing rod touches the connecting rod connecting the guide wheel on the inclinometer, it rotates upward to open. After continuing to lower, the opening and closing rod falls under the action of gravity, so that the connecting rod connecting the guide wheel of the inclinometer is located in the square clamping sub-member. Through the rotation of the clamping sub-member around the first rotating shaft, the guide wheel and the connecting rod connecting the guide wheel contract towards the center of the inclinometer tube, thereby realizing the salvage of the inclinometer. Among them, the rotation of the clamping sub-member around the first rotating shaft can be controlled by a motor. The traction rope can be an ordinary nylon rope or a steel wire rope, and a conducting wire can be attached to the traction rope.

[0009] Further, a collar with a diameter matching the cable of the slope inclinometer is arranged in the middle section of the first rotating shaft.

[0010] Ground construction personnel cannot know the specific environmental conditions in the inclinometer tube. By setting the middle section of the first rotating shaft in the form of a collar, when in use, it is sleeved on the cable of the inclinometer, which is convenient for guiding during the lowering process of the clamping member.

[0011] Further, the clamping member is provided with a fixing rod that moves horizontally.

[0012] By arranging a fixing rod that can move horizontally on the clamping member, when the clamping member reaches the position where the inclinometer to be salvaged is located, the inner side of the inclinometer tube is clamped through the horizontal movement of the fixing rod, thereby providing stable operating conditions for the entire clamping member, making the clamping member stable and non-shaking during the clamping operation, so as to improve the force application effect of the device.

[0013] Further, the clamping member is rotationally connected to the first rotating shaft through a hairspring.

[0014] The auxiliary device of the slope inclinometer provided by the utility model can adopt a motor arranged on the first rotating shaft and the motor can drive the rotation of the clamping member connected to the rotating shaft, so as to realize the clamping function of the clamping member. However, the motor will cause the structure of the device to be too large, and it is not suitable for the inclinometer tube of smaller size. The clamping of the clamping member is controlled by adopting the form of a spring, and the inward contraction of the clamping member is controlled by pulling the spring spring by a traction rope to tighten, so as to realize the clamping. This can make the structure of the device smaller and the adaptability range wider. At the same time, the traction force of the spring spring on the clamping sub-member can ensure that the clamping member maintains a certain opening and closing angle during the lowering process of the device, so that the clamping member can effectively cooperate with the inclinometer.

[0015] Furthermore, the second clamping sub-component includes a second connection side rotatably connected to the first rotating shaft and a second clamping side opposite to the second connection side. The first clamping sub-component and the second clamping sub-component have the same shape and are symmetrically arranged along the plane formed by the diameter and axis of the first rotating shaft.

[0016] The clamping member usually includes two movable parts. By setting the first clamping member and the second clamping member to have consistent and symmetrical shapes, it is ensured that the two clamping members apply force evenly during use, thereby improving the stability of the device during operation.

[0017] Furthermore, the first rotating shaft is connected to a pipe fitting, the pipeline direction of the pipe fitting is consistent with the bisector of the angle between the first clamping sub-component and the second clamping sub-component, the number of the traction ropes is two and both pass through the pipeline of the pipe fitting and are respectively connected to the first clamping side and the second clamping side.

[0018] In the auxiliary device provided by the utility model, the clamping operation of the clamping member can be completed by rotating the clamping member around the first rotating shaft, but this method requires applying a large torsional force, which increases the structural complexity of the device itself. By arranging a pipe on the clamping member and passing the traction rope through the pipe and then connecting it to the clamping side of the clamping member, the force application point is adjusted from the first rotating shaft to the clamping side, thereby reducing the size of the force required to be applied during operation and reducing the complexity of the device structure.

[0019] Furthermore, the pipe includes an inlet end and an outlet end provided with a guide member, and the traction rope is slidably connected to the guide member and is connected to the first clamping side or the second clamping side via the guide member.

[0020] By utilizing the guide piece, the traction rope will not shake radially when subjected to force, thereby avoiding the additional work loss caused by the friction between the traction rope and the outlet end of the pipe due to shaking, and also avoiding the traction rope from breaking due to the left and right shaking friction between the traction rope and the outlet end.

[0021] Further, the guiding member is a chute symmetrically arranged on the inner wall of the pipe fitting along the plane formed by the diameter and axis of the pipe fitting.

[0022] The guiding member can be a pulley or a second pipe fitting connected to the outlet end of the pipe fitting and horizontally arranged. Since the operation location of the auxiliary device provided by the present utility model is a pipeline inserted into the ground, the structure of the device needs to be as small as possible. By using a chute for guiding, the chute can be directly arranged on the inner wall of the pipe fitting, thereby reducing the structural size of the device.

[0023] Further, the number of the pipe fittings is two and they are respectively arranged at both ends of the first rotating shaft.

[0024] Two pipe fittings are provided to ensure that when the device is in use, the forces applied to the two clamping sub-members are more uniform, so as to improve the force application effect of the device.

[0025] Further, a current loop is arranged in the first clamping sub-member, and the closing and opening of the current loop are controlled by the rotation of the opening and closing rod.

[0026] By setting a current loop for the clamping member, after the clamping member is lowered and contacts the inclinometer, the opening and closing rod opens, causing the current loop to be open, thereby realizing the function of reminding the construction personnel that the auxiliary device has reached the operation position; among them, the opening and closing rod acts as a knife switch in the current loop, the wire can be attached to the towing rope and lowered together with the towing rope, and the power supply required for the current loop and the ammeter are placed on the ground and connected in series in the current loop, which is convenient for the construction personnel on the ground to observe and operate.

[0027] One or more technical solutions provided by the present utility model have at least the following technical effects or advantages:

[0028] (1) An auxiliary device for a slope inclinometer provided by the present utility model, by using a clamping member with a square frame structure and setting an opening and closing member on the sub-member on one side of the clamping member, by using a clamping member with a square frame structure and setting an opening and closing rod on the sub-member on one side of the clamping member, by using the towing rope to lower the clamping member to the position where the inclinometer is clamped. When the opening and closing rod contacts the connecting rod connecting the guide wheel on the inclinometer, it rotates upward to open. After continuing to lower, the opening and closing rod falls under the action of gravity, so that the connecting rod connecting the guide wheel of the inclinometer is located in the square clamping sub-member. Through the rotation of the clamping sub-member around the first rotating shaft, the guide wheel and the connecting rod connecting the guide wheel contract towards the center of the inclinometer tube, thereby realizing the salvage of the inclinometer.

Detailed implementation manners

[0036] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0037] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0038] Embodiment 1

[0039] Please refer to Figures 1-3 , an auxiliary device for a slope inclinometer provided by an embodiment of the present invention includes a clamping member 1 and a towing rope 2 connected to the clamping member 1. The clamping member 1 can be a claw driven by a motor, and the material of the clamping member 1 can be stainless steel or plastic. The towing rope 2 can be a nylon rope or a steel wire rope.

[0040] The clamping member 1 includes a first rotating shaft 101, a first clamping sub-member 102 and a second clamping sub-member 103 that are both rotatably connected to the first rotating shaft 101. The rotation of the first rotating shaft 101 can be driven by a motor to achieve the clamping function of the clamping member 1. As a preferred solution, the clamping member 1 is rotatably connected to the first rotating shaft 101 through a clockwork spring. By pulling the clockwork spring tight with the traction rope 2, the inward contraction of the clamping member 1 is controlled to achieve clamping, which can make the device structure smaller and have a wider adaptation range.

[0041] The first clamping sub-member 102 includes a first connection side 120 rotatably connected to the first rotating shaft 101 and a first clamping side 121 opposite to the first connection side 120. An opening and closing rod 122 is provided along the axial direction of the first clamping side 121. The opening and closing rod 122 includes a rotating end 123 rotatably connected to the first clamping side 121 and a limiting end 124 detachably connected to the first clamping side 121.

[0042] As a preferred solution, the second clamping sub-member 103 includes a second connection side 130 rotatably connected to the first rotating shaft 101 and a second clamping side 131 opposite to the second connection side 130. The first clamping sub-member 102 and the second clamping sub-member 103 have the same shape and are symmetrically arranged along the plane formed by the diameter and axis of the first rotating shaft 101. Setting the first clamping sub-member and the second clamping sub-member to have the same shape and be symmetric can ensure that when in use, the two clamping sub-members apply force evenly, thereby improving the stability of the device during operation.

[0043] Exemplarily, as Figure 3 shown, the rotating end 123 of the opening and closing rod 122 is rotatably connected to the clamping side, and the other end of the opening and closing rod 122 is detachably connected to the limiting end 124. The detachable connection can be a magnetic attraction connection or a connection by a clamping block and a clamping groove. When in use, the clamping member 1 of the auxiliary device is lowered to the position where the inclinometer is stuck by using the traction rope 2. When the opening and closing rod touches the connecting rod of the connecting pulley on the inclinometer, it rotates upward to open. After continuing to lower, the opening and closing rod falls under the action of gravity, so that the connecting rod of the connecting pulley of the inclinometer is located in the square-shaped clamping sub-member. Through the rotation of the clamping sub-member around the first rotating shaft, the pulley and the connecting rod connecting the pulley contract towards the center of the inclinometer tube, thereby realizing the fishing of the inclinometer.

[0044] When the pulley is stuck in the inclinometer tube, if directly lifted, the contact point between the pulley and the fracture of the inclinometer tube is the force application point. When pulling, the pulley is subjected to a downward force, and the pulley and the connecting rod connected to the pulley tend to expand outwards, making it difficult to lift. However, when using the auxiliary device for the inclinometer on the slope provided by the present invention, when lifting, through the clamping action of the clamping member 1 on the auxiliary device, an inward contraction force is provided for the pulley. After the pulley and the connecting rod connecting the pulley contract, then lift to complete the fishing operation.

[0045] As a preferred solution, a collar 104 is provided in the middle section of the first rotating shaft 101. The diameter of the collar 104 matches the diameter of the cable connecting the inclinometer. During use, the auxiliary device is sleeved on the cable of the inclinometer through the collar 104, thereby playing a guiding role when the auxiliary device is lowered. The collar 104 can be integrally formed with the first rotating shaft 101 or can be separately manufactured and fixedly connected to the first rotating shaft 101. The fixed connection can be welding or bonding.

[0046] As a preferred solution, a fixed rod 3 that moves horizontally is provided on the clamping member 1. The fixed rod 3 can be a telescopic rod driven by a motor. When the clamping member 1 reaches the position of the inclinometer to be salvaged, the inner side of the inclinometer tube is clamped by the horizontal movement of the fixed rod 3, thereby providing stable operating conditions for the entire clamping member 1, so that the clamping member 1 is stable and does not shake during the clamping operation, so as to improve the force application effect of the device.

[0047] Embodiment 2

[0048] Please refer to Figure 4 , an auxiliary device for a slope inclinometer provided by the present utility model on the basis of Embodiment 1. The first rotating shaft 101 is connected to a pipe fitting 4. The pipe fitting 4 can be a direction pipe or a round pipe, and the material can be stainless steel or plastic. The pipe fitting 4 can be one or two and are respectively connected to both ends of the first rotating shaft 101 to ensure that when the device is used, the force applied to the two clamping sub-members is more uniform, so as to improve the force application effect of the device. The pipe direction of the pipe fitting 4 is in the vertical direction. Specifically, an angle is formed between the end point of the first rotating shaft 101 and the side of the two clamping sub-members connected to the end point. The axis of the pipe fitting 4 coincides with the angle bisector of the angle. The number of the towing ropes 2 is two and both pass through the pipe of the pipe fitting 4 and are respectively connected to the first clamping side 121 and the second clamping side 131. By providing the pipe fitting 4 on the clamping member 1 and connecting the towing rope 2 to the clamping side of the clamping member 1 after passing through the pipe fitting 4, the force application point is adjusted from the first rotating shaft to the clamping side, thereby reducing the magnitude of the force required during operation and reducing the complexity of the device structure.

[0049] As a preferred solution, the pipe fitting 4 includes an inlet end 401 and an outlet end 402, and the outlet end 402 is provided with a guide member. The traction rope 2 enters from the inlet end 401 and passes through the outlet end 402. After being slidably connected with the guide member, it passes through the guide member and is connected to the first clamping side 121 or the second clamping side 131. The guide member can be a pulley or a second pipe fitting connected to the outlet end of the pipe fitting and horizontally arranged, wherein the inlet end 401 is located at the end point of the first rotating shaft, and the outlet end 402 is at the same height as the clamping sides of the two clamping sub-components. By utilizing the guide member, the traction rope does not radially shake when subjected to force, thereby avoiding the friction between the traction rope and the outlet end of the pipe fitting due to shaking, which causes additional work loss, and also avoids the traction rope from breaking due to left and right shaking friction between the traction rope and the outlet end.

[0050] As a preferred solution, the guide member is a slide groove which is arranged on the inner wall of the pipe and is symmetrically arranged along the plane formed by the diameter and axis of the pipe. By adopting the slide groove for guidance, the slide groove can be directly set on the inner wall of the pipe, thereby reducing the structural size of the device and being more suitable for the use scenario.

[0051] As a preferred solution, a current loop is provided in the first clamping sub-component 102, and the closing and switching of the current loop are controlled by the rotation of the opening and closing rod 122. The square frame of the first clamping sub-component 102 is an internally hollow structure for housing the wires of the current loop, wherein the opening and closing rod 122 serves as a switch of the current loop to control the opening and closing of the current loop. The traction rope is attached with the wires, which are lowered together with the traction rope 2. The power supply and ammeter required for the current loop are placed on the ground and connected in series in the current loop.

[0052] When using the auxiliary device to salvage the inclinometer, the traction rope 2 lowers the clamp 1 to the position where the inclinometer is stuck. When the opening and closing rod 122 contacts the connecting rod connected to the guide wheel on the inclinometer, it is rotated upward to open. After continuing to be lowered, the opening and closing rod falls again under the action of gravity. The operator judges the opening and closing of the opening and closing rod 122 by the current change of the ammeter, which makes it easier to know whether the auxiliary device has reached the corresponding working position, thereby improving the accuracy of the operation.

[0053] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
