Description

TECHNICAL FIELD

[0001] The utility model relates to structure test technical field, concretely, especially relates to a crane's impact collision test bench. BACKGROUND

[0002] The impact collision bench is a device for evaluating the impact damage capacity of products, which detects the impact damage capacity that the products can withstand during use by simulating the transient, high-acceleration impact and collision environment that the products may encounter in the life cycle, so as to evaluate the impact resistance of the products. In the industrial manufacturing field, many production and processing samples or materials need to be subjected to impact collision tests to obtain the performance indicators of the samples or materials, and therefore the impact collision bench needs to be used.

[0003] During the working process of the impact collision bench, the lifting mechanism of the impact collision bench can connect and lift the height of the impact body, and the sample or material to be tested is placed below the impact body. After the impact body is lifted to the preset height, the position of the impact body is limited by the locking mechanism. During the test, the locking mechanism is only opened, the impact body falls and collides with the sample or material to be tested, and the impact collision test can be completed. At present, the locking mechanism in the traditional impact collision bench generally adopts magnetic locking or buckle locking to lock the position of the impact body at the preset height. However, the existing technology has the problem of insufficient connection strength. Once the inertia force of the impact body is greater than the magnetic force, the position of the impact body cannot be locked, the heavy object will fall off instantly, and there is a safety hazard. As for the buckle locking, it is easy to appear jamming and unstable condition when releasing the impact body, and sometimes manual intervention is needed to loosen the buckle, which is inconvenient to operate.

[0004] Therefore, how to provide an impact collision test bench which can stably lock the position of the impact body and solve the jamming and unstable problem of releasing the impact body in the prior art, so that the impact body can be released stably, reduce the operation difficulty and the safety risk in the test process, has become a technical problem to be solved by the technical personnel in the field.

[0063] As Figure 3As shown, the linear guide mechanism 4 consists of two parts, which are used to connect the load impact mechanism 5 and guide the load impact mechanism 5 to move linearly in the vertical direction. In this embodiment of the utility model, the main structure of the linear guide mechanism 4 is composed of the slide rod 401 and the slider 402. The slide rod 401 is a rod-shaped object symmetrically installed on the platform 2.

The load impact mechanism 5 is connected to the slider 402 and installed between the slide rods 401, enabling the load impact mechanism 5 to move linearly along the slide rod 401.

[0064] Specifically, in an embodiment of this utility model, the load impact mechanism 5 includes: a support plate 501 disposed between the slide rods 401 and connected to the sliders 402 at both ends; a lead screw 502 disposed on the support plate 501; a first limiting nut 503 sleeved on the upper end of the lead screw 502 and abutting against the support plate 501; a counterweight 504 sleeved on the lower end of the lead screw 502; and a second limiting nut 505 sleeved on the lower end of the lead screw 502 and abutting against the counterweight 504.

[0065] like Figure 3 As shown, the load impact mechanism 5 serves as an impactor, used to collide with the test sample or material to conduct an impact collision test. In this embodiment of the invention, the main structure of the load impact mechanism 5 consists of a support plate 501, a lead screw 502, a first limiting nut 503, a counterweight 504, and a second limiting nut 505. The support plate 501 serves as the base of the mechanism, with the slider 402 connected to both ends. The lead screw 502 is vertically installed at the center of the support plate 501. The first limiting nut 503 is sleeved on the lead screw 502. The screw rod 502 is pressed tightly against the upper surface of the support plate 501 to lock the screw rod 502 onto the support plate 501 from above, preventing the support plate 501 from falling downwards. The counterweight 504 is an impact mass block, which is a metal block with a hole in the middle, and is fitted onto the lower end of the screw rod 502. By changing the weight or number of counterweights 504, the magnitude of the impact energy can be adjusted. The second limiting nut 505 is located at the lowest end of the screw rod 502 and is pressed tightly against the lower surface of the counterweight 504 to support and lock the counterweight 504 from below, preventing it from loosening or falling off during the impact.

[0066] Specifically, in an embodiment of this utility model, the first traction mechanism 8 includes: a linear bearing sleeved on the optical axis 7; a lifting reel 801 sleeved on the linear bearing; and a lifting wire 802 connected at one end to the lifting reel 801 and at the other end to the load impact mechanism 5.

The main structure of the first traction mechanism 8 includes a linear bearing, a lifting reel 801, and a lifting wire 802. The linear bearing is mounted on the optical shaft 7, and the lifting reel 801 is sleeved on the linear bearing. Using the linear bearing, the lifting reel 801 can rotate relative to the optical shaft 7. The lifting wire 802 serves as a connector, with one end fixed to the lifting reel 801 and the other end connected to the top of the lead screw 502. When the lifting reel 801 rotates, the lifting wire 802 lifts or releases the load impact mechanism 5.

[0068] Specifically, in an embodiment of this utility model, the sliding gear clutch 10 includes: a clutch internal gear ring 1001 disposed on the right side wall of the lifting winding reel 801; and a clutch external cylindrical gear 1002 disposed on the left side wall of the transmission mechanism 9, which meshes with or separates from the clutch internal gear ring 1001.

[0069] like Figure 4As shown, in the embodiment of the utility model, the sliding gear clutch 10 is the core control unit of the first traction mechanism 8, its essence is a gear clutch that realizes "combination" and "separation" through axial sliding, it is composed of the clutch inner gear ring 1001 and the clutch outer cylindrical gear 1002, the clutch inner gear ring 1001 is installed on the right side wall of the lifting winding wheel 801, and the clutch outer cylindrical gear 1002 is installed on the left side wall of the transmission mechanism 9; when working, there are two states of combination and separation, when being in the combined state, i.e. when the load impact mechanism 5 needs to be lifted, the clutch outer cylindrical gear 1002 is pulled to the left side, so that it is completely engaged with the clutch inner gear ring 1001, at this time, the power transmission path of the driving mechanism 11 is: first driving motor 1102-transmission mechanism 9-clutch outer cylindrical gear 1002-clutch inner gear ring 1001-lifting winding wheel 801, so that the lifting winding wheel 801 can rotate, and the lifting steel wire 802 is retracted, so that the impact body is lifted; when the combined state needs to be adjusted to the separated state, i.e. when the impact body needs to be released after being lifted to the predetermined height, the clutch outer cylindrical gear 1002 is pushed to the right side, so that it is disengaged from the clutch inner gear ring 1001, at this time, the power transmission path is cut off, the lifting winding wheel 801 is disconnected from the transmission system, and is in a free state, the load impact mechanism 5 falls under the action of gravity and drags the lifting steel wire 802, so that the lifting winding wheel 801 rotates freely, and the impact is completed.

[0070] Specifically, in the embodiment of the utility model, the mounting bracket 3 comprises: a first cross beam, a second cross beam and a third cross beam which are arranged in parallel with each other at the top end of the rack 1; U-shaped brackets which are symmetrically arranged above the first cross beam and the third cross beam; and a fourth cross beam which is arranged between the U-shaped brackets.

[0071] Specifically, in the embodiment of the utility model, the transmission mechanism 9 comprises: a first transmission gear 901 which is sleeved on the optical axis 7; and a bearing seat 902 which is arranged on the right side wall of the first transmission gear 901.

[0072] Specifically, in the embodiment of the utility model, the driving mechanism 11 comprises: a first motor bracket 1101 which is arranged on the bottom surface of the fourth cross beam; a first driving motor 1102 which is arranged on the first motor bracket 1101; and a second transmission gear 1103 which is arranged on the output end of the first driving motor 1102 and is engaged with the transmission mechanism 9.

[0073] Specifically, in this embodiment of the present invention, the drive mechanism 11 is used to provide the initial driving force, and it consists of the first motor bracket 1101, the first drive motor 1102, and the second transmission gear 1103. The first motor bracket 1101 is mounted on the mounting bracket 3, and the first drive motor 1102 is mounted on the first motor bracket 1101. It is used to provide controllable power. The second transmission gear 1103 is provided on the output shaft of the first drive motor 1102. The second transmission gear 1103 meshes with the transmission mechanism 9 and can transmit the output power of the first drive motor 1102 to the transmission mechanism 9, thereby driving the transmission mechanism 9 to perform a fixed-axis rotational motion.

[0074] Specifically, in an embodiment of this utility model, the limiting block 12 is provided with a through hole.

[0075] Specifically, in an embodiment of this utility model, the second traction mechanism 14 includes: a second motor bracket 1401 disposed on the side wall of the third crossbeam; a second drive motor 1402 disposed on the second motor bracket 1401; a clutch winding reel 1403 disposed at the output end of the second drive motor 1402; and a clutch wire 1404 disposed on the clutch winding reel 1403. One end of the clutch wire 1404 is connected to the clutch winding reel 1403, and the other end passes through the through hole and is connected to the bearing seat 902.

[0076] like Figure 2 As shown, in this embodiment of the present invention, the second traction mechanism 14 is used to perform a release action, separating the clutch internal gear ring 1001 from the clutch external cylindrical gear 1002. In this embodiment, the main structure of the second traction mechanism 14 consists of the second motor bracket 1401, the second drive motor 1402, the clutch winding reel 1403, and the clutch steel wire 1404. Since the default state of the sliding gear clutch 10 under the action of the compression spring 13 is the meshing state, i.e., the combined state, state adjustment is performed. The section requires the control unit, namely the second traction mechanism 14; when release is needed, the second drive motor 1402 starts, retracts the clutch wire 1404, and the clutch wire 1404 drives the clutch external cylindrical gear 1002 to move to the right on the optical axis 7. The clutch external cylindrical gear 1002 separates from the clutch internal gear ring 1001. At this time, the power of the load impact mechanism 5 is cut off, and the load impact mechanism 5 falls under the action of gravity, dragging the lifting wire 802, so that the lifting winding wheel 801 rotates freely, completing the impact.

[0077] Specifically, in the embodiment of the utility model, the application process of the impact collision test bench is: the sample or material to be tested is placed on the placing table 2 and placed below the load impact mechanism 5; then the driving mechanism 11 is started to provide rotary power to drive the transmission mechanism 9 to rotate; at the same time, under the action of the compression spring 13, the clutch inner gear ring 1001 is engaged with the clutch outer cylindrical gear 1002, when the transmission mechanism 9 rotates, the lifting winding wheel 801 is driven to rotate, the lifting steel wire 802 is retracted on the lifting winding wheel 801, so as to drive the load impact mechanism 5 to lift upward, when the load impact mechanism 5 is lifted to the preset height, the driving mechanism 11 is closed instantly, and the load impact mechanism 5 can be locked at the preset height; then, the second traction mechanism 14 is started, the clutch steel wire 1404 is retracted on the clutch winding wheel 1403, the compression spring 13 is continuously compressed, at this time, the structure composed of the clutch outer cylindrical gear 1002, the transmission mechanism 9 and the bearing seat 902 is linearly displaced on the optical axis 7 under the tension of the clutch steel wire 1404, the clutch inner gear ring 1001 is separated from the clutch outer cylindrical gear 1002, the load impact mechanism 5 loses the locking force and performs free fall motion, collides with the sample or material to be tested below, and the impact collision test is completed.

[0078] From above, the utility model discloses the impact collision test platform, aiming at solving the traditional impact collision instrument cannot buckle locking impact body, and the problem of unstable when releasing impact body.

The installation position of the load impact mechanism 5 is above the sample or material to be tested. Under the action of external force, the load impact mechanism 5 can perform free fall motion and collide with the sample or material to be tested below, and impact collision test is carried out. Secondly, two fixed blocks 6 are symmetrically arranged on the mounting support 3, and the optical axis 7 is installed between the fixed blocks 6.
