The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0025] Example 1:
[0026] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a flexible adjustable shaft-type anti-torsional loading device. Figure 2 This is a schematic diagram of the installation of an insert-type loading rod. Figure 3 This is a front view of the weight block. This utility model provides a flexible, adjustable shaft-type anti-torsional loading device: it includes a loading wrench 101 and auxiliary components. The auxiliary components include a loading basket 102, a guide column 103, a rotating lifting ring 104, a fixed lifting ring 105, a weight block 106, reinforcing components, mounting components, and removal components. The reinforcing components include a first reinforcing column 108 and a second reinforcing column 109. The mounting components include a U-shaped seat 110 and a connector 111. The removal components include a left hanging ear 112 and a right hanging ear 113. The aforementioned solution solves the problem in existing testing devices where the counterweight structure is inconvenient to add or combine during testing, making counterweight adjustment very difficult. This solution facilitates counterweight adjustment.
[0027] In this embodiment, the loading wrench 101 is rotatably mounted on one side of the test bench. The loading wrench 101 is used to insert the insert-type loading rod 107, and then rotates under the weight of the loading basket 102, finally driving the shaft test piece to rotate to achieve detection.
[0028] Preferably, the loading basket 102 is located below the rear of the insertable loading rod 107, the guide post 103 is fixedly connected to the loading basket 102 and is symmetrically arranged, the rotating lifting ring 104 is installed on both sides of the top of the loading basket 102 through the mounting component, the fixed lifting ring 105 is welded to the end of the insertable loading rod 107 away from the loading wrench 101 and is connected to the rotating lifting ring 104 through the lifting rope device, the weight block 106 is slidably connected to the guide post 103 and is vertically overlapped, the reinforcing component is arranged on the loading basket 102, and the removal component is arranged on both sides of the weight block 106. The bottom disc of the guide post 103 is sunk into the non-penetrating stepped cavity on the flat plate at the bottom of the loading basket 102, and then fixed by countersunk bolts. The suspension rope device consists of hooks and steel wire rope or hemp rope. Hooks are fixedly connected to both sides of the steel wire rope or hemp rope. The upper hook is hung on the fixed lifting ring 105, and the bottom hook is hung on the connecting rope between the rotating lifting ring 104, thereby suspending the loading basket 102. The weight block 106 can be set with different weights to facilitate combination use when counterweighting.
[0029] Preferably, the first reinforcing column 108 is welded to the left and right sides of the loading basket 102; the second reinforcing column 109 is welded to the front and rear sides of the loading basket 102. The first reinforcing column 108 and the second reinforcing column 109 are welded and fixed to enhance the stability of the loading basket 102.
[0030] Preferably, the U-shaped seat 110 is welded to the top of the loading basket 102 and is symmetrically arranged; the connecting piece 111 is detachably connected to the U-shaped seat 110 and the rotating lifting ring 104 respectively. The U-shaped cavity on the U-shaped seat 110 is provided with the U-shaped part of the bottom of the rotating lifting ring 104, which facilitates installation through the connecting piece 111. Both the U-shaped seat 110 and the rotating lifting ring 104 are provided with alignment through holes for installation.
[0031] Preferably, the connector 111 adopts a T-shaped screw and nut structure or a slotted pin and nut structure. When a slotted pin is used, the nuts on both sides limit the pin, and the smooth shaft of the pin facilitates the limiting of the rotating lifting ring 104. Furthermore, hexagonal grooves are provided on both ends of the pin to prevent rotation during nut installation.
[0032] Preferably, the left hanging lug 112 is welded to the left side of the weight block 106; the right hanging lug 113 is welded to the right side of the weight block 106. Both the left hanging lug 112 and the right hanging lug 113 have through holes, allowing the operator to install or remove the weight block 106 by using an L-shaped lifting hook in conjunction with the left and right hanging lugs 112 and 113.
[0033] Preferably, there are two fixing rings 105, which are spaced apart from each other.
[0034] Preferably, a locking structure is provided on the insertion tube of the insert loading rod 107 and the loading wrench 101. The locking structure (not shown in the figure) uses a T-shaped screw and a nut. After the insert loading rod 107 and the loading wrench 101 are fully inserted and locked, a through hole is drilled between the insert loading rod 107 and the loading wrench 101. When drilling the through hole, it is necessary to ensure that the fixing ring 105 is located at the rear obliquely below the insert loading rod 107. Then, the T-shaped screw is inserted, and finally the nut is installed. This structure prevents the insert loading rod 107 from detaching from the loading wrench 101 during testing.
[0035] When using this utility model to solve the problem of inconvenient addition or combination of counterweight structures in existing testing devices, resulting in significant inconvenience in counterweight adjustment during testing, the shaft-type test piece is first fixed on the test platform. Then, the suspension rope device is connected to the connecting ropes on the top of the two rotating rings 104 to suspend the loading basket 102. Further, the insertable loading rod 107 is inserted into the connecting pipe of the loading wrench 101. Finally, the weight blocks 106 are added one by one through the guide post 103, and the addition is based on… The ability to combine weights of different amounts greatly facilitates the weight adjustment of the counterweight device. When the loading basket 102 contains different numbers and weights of the weight blocks 106, the torque is transmitted to the torque meter via the insert loading rod 107 and the loading wrench 101. The torque is then transmitted to the transmission shaft (test piece) via the connecting flange. The test piece shaft generates an anti-torsional torque, and the digital torque meter displays the specific torque value. This solves the problem that in existing testing devices, the counterweight structure is not convenient to add or combine flexibly during testing, making counterweight adjustment very inconvenient.

The flexible adjustable shaft anti-torsion loading device further includes a stabilizing component, which includes a left triangular block 201 and a right triangular block 202.
[0038] The left triangular block 201 is welded and fixed to both the loading basket 102 and the U-shaped seat 110; the right triangular block 202 is welded and fixed to both the loading basket 102 and the U-shaped seat 110, and is symmetrically arranged with the left triangular block 201. The welding of the left triangular block 201 and the right triangular block 202 is used to improve the stability of the U-shaped seat 110.
[0039] Secondly, the bottom of the left triangular block 201 and the right triangular block 202 are each provided with a circular post, which can be slidably inserted into the positioning hole of the top support arm of the loading basket 102. This structure helps to improve the stability of the left triangular block 201 and the right triangular block 202 after installation.
[0040] Finally, a stabilizing component 203 is welded and fixed between the left triangular block 201 and the right triangular block 202. The stabilizing component 203 is a straight round rod or a square rod, with both ends welded and fixed respectively.
[0041] In this embodiment, the stability of the U-shaped seat 110 can be improved by setting the left triangular block 201 and the right triangular block 202.
