Description

Technical Field

[0001] This utility model relates to the field of maintenance tooling technology, and more specifically, to a portable tool maintenance bracket. Background Technology

[0002] When inspecting, maintaining, or attaching / removing long rod-like workpieces, such as BHAs (Bottom Hole Assemblies), it is necessary to keep them suspended and able to rotate freely in order to perform 360° inspection and maintenance.

[0003] In existing technologies, there are no dedicated auxiliary tools. In actual operation, long rod-shaped workpieces can only be placed on the ground. When rotating for inspection, they will roll, and the surface attachments will come into contact with the ground, causing damage or affecting the rotation of the workpiece. When fastening or unfastening the BHA, special tools are required, such as pipe wrenches or chain wrenches. This requires a certain gap between the BHA and the ground to allow the pipe wrench or chain wrench to be inserted. However, the gap between the BHA placed directly on the ground and the ground is too small to meet the insertion requirements of the pipe wrench or chain wrench. Therefore, the BHA needs to be lifted to insert the pipe wrench or chain wrench. Furthermore, when rotating and tightening the BHA, the workpiece rubs against the ground, increasing the rotational resistance and causing wear on the workpiece surface.

[0004] In summary, how to solve the problems of wear and difficulty in turning long rod-shaped workpieces during maintenance is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] The core of this utility model is to provide a portable tool maintenance bracket. By combining the base and the wheeled rotating part, it supports long rod-shaped workpieces and reduces their turning resistance, making it easy to turn the workpiece 360° for maintenance. During the turning process, the workpiece does not come into contact with the ground surface, effectively reducing the wear on the workpiece surface.

[0047] Please refer to Figure 1 A portable tool maintenance stand, comprising:

[0048] Base section 1;

[0049] At least two sets of wheel-type rotating parts 3 are rotatably mounted on the top of the base part 1. The rotation axes of two adjacent sets of wheel-type rotating parts 3 are parallel, and the shaft spacing between two adjacent sets of wheel-type rotating parts 3 is adjustable.

[0050] like Figure 1As shown, the maintenance bracket is formed by combining the base part 1 and at least two sets of wheeled rotating parts 3. It has the advantages of small size, light weight and no limitation on the application scenario, and can be widely used in different working conditions.

[0051] Moreover, during use, long rod-shaped workpieces are lifted above the two adjacent sets of wheeled rotating parts 3, and the outer periphery of the workpiece simultaneously comes into contact with the outer periphery of the two adjacent sets of wheeled rotating parts 3. When the workpiece is rotated, the wheeled rotating parts 3 move accordingly, thereby reducing the rotational resistance of the workpiece. Furthermore, there is no limitation on the rotation angle of the workpiece, which meets the requirement of 360° rotation for maintenance.

[0052] In some embodiments, the wheel-type rotating part 3 is a support wheel or support cylinder that is rotatably mounted by bearings. In some embodiments, an elastic rubber layer is attached to the outer periphery of the support wheel or support cylinder to increase the frictional resistance between the workpiece and the wheel-type rotating part 3 and reduce the vibration transmission between the workpiece and the wheel-type rotating part 3.

[0053] In some embodiments, the base portion 1 is a frame structure, and a bearing seat 2 is provided on the top for rotatably mounting the wheel-type rotating portion 3.

[0054] like Figure 1 As shown, the base 1 is made of square steel plate and the support frame is made of angle iron. The overall structure is simple, stable, and easy to carry and use.

[0055] Meanwhile, the wheel-type rotating part 3 is installed on its top through the bearing seat 2, reducing the assembly difficulty.

[0056] In some embodiments, a strip-shaped hole 11 is provided on the top of the base portion 1, the length direction of the strip-shaped hole 11 is horizontal and perpendicular to the axis of the wheel-type rotating portion 3;

[0057] The bearing housing 2 is fixedly connected to the strip hole 11 by bolts.

[0058] like Figure 2 As shown, a strip hole 11 is provided on the top of the base part 1, so that when the bearing seat 2 is connected to the base part 1, the position can be finely adjusted to change the shaft spacing between two adjacent sets of wheel-type rotating parts 3, so as to adapt to the use of long rod-type workpieces of different specifications.

[0059] In some embodiments, the bearing housing 2 and the base portion 1 are slidably mounted in the horizontal direction, and the sliding direction of the bearing housing 2 is perpendicular to the axial direction of the wheel-type rotating portion 3.

[0060] A locking assembly is provided in the base portion 1 and / or the bearing housing 2 to lock the relative position of the base portion 1 and the bearing housing 2.

[0061] like Figure 3As shown, the bearing housing 2 and the base part 1 are slidably installed, which facilitates the adjustment of the shaft spacing between two adjacent sets of bearing housings 2, so as to adapt to the use of more long rod-like workpieces of various specifications.

[0062] Meanwhile, a locking assembly is used to lock and limit the bearing housing 2 and the base part 1 to ensure that the relative positions of the bearing housing 2 and the base part 1 are stable during use.

[0063] In some embodiments, the locking assembly includes an eccentric wheel 21, which is rotatably connected to the base portion 1, and the bearing seat 2 is disposed between the base portion 1 and the outer peripheral surface of the eccentric wheel 21.

[0064] When the outer circumferential surface of the distal end of the eccentric wheel 21 abuts against the bearing housing 2, the eccentric wheel 21 can press the bearing housing 2 into place on the surface of the base portion 1.

[0065] like Figure 3 As shown, an eccentric wheel 21 rotatably mounted to the base 1 is used as a locking component. When the non-long diameter end of the eccentric wheel 21 abuts against the bearing seat 2, the normal pressure between the bearing seat 2 and the base 1 is small, that is, the frictional force of the relative movement between the two is small, which can change the relative position relationship between the two, that is, adjust the axial distance between two adjacent sets of bearing seats 2. When the outer circumferential surface of the far diameter end of the eccentric wheel 21 abuts against the bearing seat 2, the bearing seat 2 is pressed against the surface of the base 1, the normal pressure between the two increases, the frictional resistance of the relative movement increases, and thus the relative movement between the two is suppressed, that is, the relative position locking of the bearing seat 2 and the base 1 is achieved.

[0066] In some embodiments, the locking assembly includes a limiting hole and several sets of positioning holes. The limiting hole is disposed in the bearing seat 2, and several sets of positioning holes are arranged sequentially on the surface of the base portion 1 along the sliding direction of the bearing seat 2. The limiting hole can be fixed by inserting a pin into the positioning hole at the corresponding position.

[0067] By providing a limiting hole on the bearing housing 2 and a positioning hole on the base part 1, when the bearing housing 2 and the base part 1 move to their corresponding relative positions, the bearing housing 2 and the base part 1 can also be locked by inserting a pin.

[0068] In some embodiments, the bearing housing 2 and the base portion 1 are slidably mounted in the horizontal direction, and the sliding direction of the bearing housing 2 is perpendicular to the axial direction of the wheel-type rotating portion 3.

[0069] The base 1 is provided with a first adjustment part 4, which is used to adjust the shaft spacing between two adjacent sets of wheel-type rotating parts 3.

[0070] like Figure 4As shown, by providing a first adjustment part 4 inside the base part 1, the shaft spacing between two adjacent sets of wheel-type rotating parts 3 can be adjusted. At the same time, the self-locking capability of the first adjustment part 4 can be used to ensure the relative position of the bearing seat 2 and the base part 1 is stable during operation.

[0071] In some embodiments, the first adjustment part 4 includes a first lead screw 42 and a first handwheel 41 disposed at the end of the first lead screw 42;

[0072] The first lead screw 42 is rotatably connected to the base part 1, and the length direction of the first lead screw 42 is consistent with the sliding direction of the bearing seat 2. The first lead screw 42 is connected to the two adjacent sets of wheel-type rotating parts 3 by threads with opposite directions of rotation.

[0073] like Figure 4 As shown, a handwheel or other power source is used to drive the first lead screw 42 to rotate. By using the opposite direction of the thread connecting the first lead screw 42 to the two adjacent sets of bearing seats 2, the distance between the shafts of the two adjacent sets of wheel-type rotating parts 3 can be adjusted by using the first lead screw 42 to drive the shafts of the two adjacent sets of wheel-type rotating parts 3. At the same time, the self-locking ability of the lead screw assembly ensures that the relative position of the two adjacent sets of wheel-type rotating parts 3 is stable during operation.

[0074] In some embodiments, the base portion 1 includes a bottom platform 12 and a mounting platform 13 that are slidably mounted relative to each other in a vertical direction;

[0075] The wheel-type rotating part 3 is rotatably connected to the mounting platform 13;

[0076] A second adjustment part 5 is provided between the mounting platform 13 and the bottom platform 12 for adjusting the distance between the two.

[0077] For long rod-shaped workpieces, support is required at both ends during maintenance. When the workpiece is too long, the middle part will bend downwards. To solve this problem, several support points need to be added in the middle of the rod, that is, the number of maintenance supports needs to be increased.

[0078] For work conditions with uneven ground, adjusting the height of the maintenance support can reduce the downward bending of the workpiece in the middle.

[0079] like Figure 5 As shown, the base 1 is divided into upper and lower parts, namely the mounting platform 13 and the bottom platform 12, which are slidably installed in the vertical direction. The distance between the two parts is adjusted by the second adjustment part 5 to adjust the overall support height of the maintenance bracket.

[0080] In some embodiments, the second adjustment part 5 includes a drive shaft 53 and a plurality of second lead screws 52;

[0081] The drive shaft 53 is horizontal in the axial direction. The drive shaft 53 is connected to all the second lead screws 52 through a bevel gear pair. A second handwheel 51 is provided at the end of the drive shaft 53.

[0082] The second lead screw 52 and the drive shaft 53 are both rotatably mounted to the bottom platform 12, and the axial direction of the second lead screw 52 is consistent with the relative movement direction of the bottom platform 12 and the mounting platform 13, and the second lead screw 52 is connected to the mounting platform 13 by a thread.

[0083] or,

[0084] The second lead screw 52 and the drive shaft 53 are both rotatably mounted on the mounting platform 13, and the axial direction of the second lead screw 52 is consistent with the relative movement direction of the bottom platform 12 and the mounting platform 13, and the second lead screw 52 is connected to the bottom platform 12 by a thread.

[0085] like Figure 5 As shown, a second lead screw 52 is provided between the bottom platform 12 and the mounting platform 13. By rotating the second lead screw 52, ​​the distance between the two can be adjusted, thereby changing the support height of the maintenance bracket. The second lead screw 52 transmits power to the transmission shaft 53 through a bevel gear pair. The transmission shaft 53 enables the synchronous rotation of multiple sets of second lead screws 52, avoiding jamming when adjusting the height of the maintenance bracket.

[0086] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
