Description

Technical Field

[0001] This invention belongs to the technical field of gate regulator testing equipment, and specifically relates to an automatic disassembly and assembly device for the test lever head of a gate regulator. Background Technology

[0002] The brake adjuster (automatic brake shoe clearance adjuster) is a key component of the railway freight car braking system. It is used to automatically adjust the clearance between the brake shoe and the wheel tread during braking to ensure stable and reliable braking performance. Before leaving the factory, the brake adjuster needs to undergo various performance tests on a dedicated test bench to verify its performance. Before the test, the brake adjuster needs to be connected to the test bench through a test tie rod head, and tensile and compressive loads are applied through the test tie rod head to simulate actual operating conditions.

[0003] During the brake adjuster testing process, the installation and disassembly of the test lever head are mainly done manually. Operators must manually connect the test lever head to the brake adjuster and tighten or loosen the connecting threads using tools such as wrenches. This process is labor-intensive, inefficient, and carries quality risks such as thread damage and improper connection. Furthermore, due to the significant weight of the test lever head and the limited operating space, manual assembly and disassembly pose certain safety hazards. In addition, with the increasing production and maintenance volume of railway freight cars, higher demands are placed on the efficiency of brake adjuster testing, and the existing manual assembly and disassembly methods are no longer sufficient to meet the needs of batch testing.

[0004] Therefore, how to improve experimental efficiency, reduce labor intensity, and ensure experimental quality and operational safety is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an automatic disassembly and assembly device for the test lever head of the brake adjuster, which can not only improve test efficiency and reduce labor intensity, but also ensure test quality and operational safety.

[0044] In view of this, the core of the present invention is to provide an automatic disassembly and assembly device for the test lever head of the brake adjuster, which can not only improve test efficiency and reduce labor intensity, but also ensure test quality and operational safety.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Please refer to [the accompanying drawings]. Figures 1-7 .

[0046] The automatic disassembly and assembly device for the test pull rod head of the brake adjuster disclosed in this embodiment of the invention includes a test bench 100 and mounting mechanisms 200 respectively disposed at both ends of the test bench 100. The mounting mechanisms 200 are respectively connected to the test pull rod heads 400 of the brake adjuster 300 disposed at both ends of the brake adjuster 300.

[0047] The installation mechanism 200 includes a support plate 201, a sliding plate 202, and a tightening assembly 203. The support plate 201 is slidably connected to the test bench 100 and can slide along the vertical direction of the test bench 100. The sliding plate 202 is slidably connected to the support plate 201 and can slide horizontally on the support plate 201. The tightening assembly 203 is fixed on the sliding plate 202 and can slide towards or away from the test lever head 400 of the brake adjuster under the action of the sliding plate 202, so as to connect or disconnect with the test lever head 400 of the brake adjuster.

[0048] When testing the brake adjuster 300, the brake adjuster 300 and the brake adjuster test pull rod heads 400 located at both ends of the brake adjuster 300 need to be placed on the test bench 100. Then, the mounting mechanisms 200 located at both ends of the test bench 100 are controlled to connect one-to-one with the brake adjuster test pull rod heads 400 at both ends of the brake adjuster 300. First, the support plate 201 is controlled to slide vertically along the test bench 100 to the first preset position. Then, the sliding plate 202 is controlled to drive the tightening assembly 203 to move horizontally toward the support plate 201. The test lever head 400 of the brake adjuster slides in the direction, so that the tightening component 203 reaches the second preset position and connects with the test lever head 400 of the brake adjuster; after the brake adjuster 300 is tested, the control support plate 201 slides in the vertical direction of the test bench 100 to the first initial position, and then the control slide plate 202 drives the tightening component 203 to slide in the horizontal direction away from the test lever head 400 of the brake adjuster on the support plate 201, so that the tightening component 203 reaches the second initial position, thereby disengaging from the test lever head 400 of the brake adjuster.

[0049] Compared with the manual operation disclosed in the prior art, the automatic disassembly and assembly device for the test lever head of the gate adjuster disclosed in the embodiments of the present invention can not only improve the test efficiency and reduce the labor intensity, but also ensure the test quality and operation safety.

[0051] The support plate 201 includes a horizontal plate 2012 and a vertical plate 2011 that are vertically connected. The vertical plate 2011 is slidably connected to the first slide rail via a first slider, and the slide plate 202 is disposed on the horizontal plate 2012.

[0052] As a further embodiment, the mounting mechanism 200 disclosed in this embodiment of the invention also includes a first driving member 206.

[0053] The first driving component 206 includes a first fixed end and a first driving end. The first fixed end is fixed on the test bench 100, and the first driving end is connected to the vertical plate 2011.

[0054] When the first driving component 206 is activated, the first driving end of the first driving component 206 drives the vertical plate 2011 to slide along the vertical direction of the test bench 100 toward the direction close to the test lever head 400 of the brake adjuster, thereby causing the horizontal plate 2012 to slide in the vertical direction toward the direction close to the test lever head 400 of the brake adjuster.

[0055] As a further embodiment, the installation mechanism 200 disclosed in this embodiment of the invention further includes a second driving member 207, which includes a second fixed end and a second driving end.

[0056] The horizontal plate 2012 is also provided with a second sliding component. There are two sets of the second sliding components, which are respectively located on the two edges of the horizontal plate 2012. An avoidance through hole is also provided between the two sets of the second sliding components.

[0057] The second fixed end is fixed to the lower end face of the horizontal plate 2012, and the second driving end is provided with a connecting plate, which passes through the clearance hole and connects to the slide plate 202.

[0058] It should be noted that the second sliding component includes a second slide rail and a second slider. The second slide rail is fixed on the horizontal plate 2012, and one side of the second slider is connected to the slide plate 202, while the other side is slidably connected to the second slide rail.

[0059] The second drive component 207 is activated, and the second drive end of the second drive component 207 moves horizontally toward the direction of approaching the test lever head 400 of the brake adjuster, thereby causing the slide plate 202 to move horizontally toward the direction of approaching the test lever head 400 of the brake adjuster, so that the tightening component 203 reaches the second preset position to achieve connection with the test lever head 400 of the brake adjuster.

[0060] The specific structure of the tightening component 203 is not limited in the embodiments of the present invention. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0061] As a specific embodiment of the present invention, the tightening assembly 203 disclosed in the present invention includes a tightening motor 2031, a reducer 2032, a transmission assembly and a tightening gear assembly.

[0062] The transmission assembly includes a first driving gear 2034, a first driven gear 2035, and a second driven gear 2036.

[0063] The tightening motor 2031, the reducer 2032 and the first driving gear 2034 are connected in sequence. The first driven gear 2035 and the second driven gear 2036 are both meshed with the first driving gear 2034 and can drive the tightening assembly 203 to tighten the test lever head 400 of the brake adjuster.

[0064] Start the tightening motor 2031, which transmits power to the reducer 2032. The reducer 2032 transmits power to the first drive gear 2034, which drives the second drive gear 2034 to rotate. The second drive gear 2034 drives the tightening gear assembly to rotate, which in turn drives the brake adjuster test lever head 400 to rotate, so that the brake adjuster test lever head 400 is tightened with the brake adjuster 300 and the mounting mechanism 200 respectively for testing.

[0065] In order to protect the transmission components and prevent them from being interfered with or damaged during operation, the mounting mechanism 200 disclosed in the embodiments of the present invention further includes a mounting housing 2033, wherein the transmission components are disposed within the mounting housing 2033.

[0066] The embodiments of the present invention do not limit the specific structure of the tightening gear assembly. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0067] As a specific embodiment of the present invention, the tightening gear assembly disclosed in the present invention includes a tightening gear body 2037, a tightening gear meshing part 2038, a first retaining ring 2039, and a second retaining ring 2040.

[0068] The first retaining ring 2039 and the second retaining ring 2040 are both located inside the mounting housing 2033. Both the first retaining ring 2039 and the second retaining ring 2040 have a slot for the brake adjuster test pull rod head 400 to pass through. The slot is located outside the mounting housing 2033, and there is a gap between the first retaining ring 2039 and the second retaining ring 2040.

[0069] The tightening gear body 2037 is disposed inside the first retaining ring 2039 and the second retaining ring 2040.

Both the tightening gear body 2037 and the tightening gear meshing part 2038 are provided with corresponding openings, and both the first driven gear 2035 and the second driven gear 2036 mesh with the tightening gear meshing part 2038.

[0070] Start the tightening motor 2031, and the tightening motor 2031 rotates forward. The tightening motor 2031 drives the transmission component to rotate through the reducer 2032. The transmission component drives the tightening gear body 2037 and the tightening gear meshing part 2038 to rotate, so that the openings of the tightening gear body 2037 and the tightening gear meshing part 2038 correspond to the openings of the first retaining ring 2039 and the second retaining ring 2040. Then, start the first driving member 206, so that the first driving member 206 reaches the first preset position. Then, start the second driving member 207, so that the tightening component 203 reaches the second preset position, so that the brake adjustment test pull rod head 400 of the brake adjuster 300 passes through the retainer and the opening and engages with the tightening gear body 2037.

[0071] Start the tightening motor 2031. The tightening motor 2031 reverses and drives the transmission component to rotate through the reducer 2032. The transmission component drives the main body of the tightening gear 2037 and the meshing part of the tightening gear 2038 to rotate, so that the opening of the main body of the tightening gear 2037 and the meshing part of the tightening gear 2038 is misaligned with the first retaining ring 2039 and the second retaining ring 2040. The first retaining ring 2039 and the second retaining ring 2040 block the opening of the main body of the tightening gear 2037. The tightening motor 2031 continues to reverse, which can realize the tightening of the brake adjuster 300 and the test pull rod head 300 of the brake adjuster.

[0072] To save space and facilitate the arrangement of the transmission components and tightening gear assembly, the diameter of the driving gear 2034 disclosed in the embodiments of the present invention is R1, and the diameters of the first driven gear 2035 and the second driven gear 2036 are both R2, where R1 > R2.

[0073] In a preferred embodiment, the automatic disassembly and assembly device for the test lever head of the gate regulator disclosed in this embodiment of the invention has 1 / 2R1=R2.

[0074] As a further embodiment, the installation mechanism 200 disclosed in this embodiment of the invention also includes a bracket 209, one end of which is connected to the slide plate 202 and the other end of which is connected to the reducer 2032.

[0075] Among them, the bracket 209 has a U-shaped structure, and the bracket 209 can effectively fix the tightening motor 2031 and the reducer 2032.

[0076] As a further embodiment, the installation mechanism 200 disclosed in this embodiment of the invention further includes a clamping component 204, which is disposed on the slide plate 202.

[0077] The clamping assembly 204 includes a fixing plate 2041, a third driving member 2044, a first clamping part 2042, a second clamping part 2043, and a third driving member 2044. The third driving member 2044 includes a first driving rod and a second driving rod. The first driving rod is connected to the first clamping part 2042, and the second driving rod is connected to the second clamping part 2043.

[0078] The first clamping part 2042 and the second clamping part 2043 are slidably disposed on the fixed plate 2041.

[0079] When the third drive unit 2044 is activated, the first and second drive rods of the third drive unit 2044 extend. The first drive rod pushes the first clamping part 2041, and the second drive rod pushes the second clamping part 2043 away from each other. At this time, the end of the test pull rod head 400 of the brake adjuster can be placed between the first clamping part 2042 and the second clamping part 2043. Then, the third drive unit 2044 is closed, so that the first clamping part 2042 and the second clamping part 2043 move closer to each other to achieve clamping of the test pull rod head 400 of the brake adjuster.

[0080] As a further embodiment, the installation mechanism 200 disclosed in this embodiment of the invention also includes a fourth driving member, a third sliding assembly, and a rotary hydraulic cylinder 208.

The third slide rail is set on the table surface. The corner hydraulic cylinder 208 is fixed on the third slider. The fourth driving component is set under the table surface and passes through the through groove to connect with the corner hydraulic cylinder 208.

[0083] When the test lever head 400 of the brake adjuster is tightened, the fourth drive component can be activated. The fourth drive component drives the angle hydraulic cylinder 208 to slide on the third slide rail to the third preset position. At this time, the angle hydraulic cylinder 208 is activated to press the brake adjuster 300, and then the installation mechanism 200 is activated to achieve the fastening of the test lever head 400 of the brake adjuster to the brake adjuster 300, and the fastening of the test lever head 404 of the brake adjuster to the installation mechanism 200.
