Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, and in particular to sliding counterweight mechanisms. Background Technology

[0002] A sliding counterweight mechanism is a device that dynamically adjusts the position of a mechanical system by sliding a counterweight along a preset trajectory (such as a guide rail or groove) to achieve torque balance and load optimization. It typically consists of a sliding counterweight and a guide component.

[0003] Traditional fixed counterweight mechanisms have significant drawbacks in practical applications. The main problem lies in the mechanical connection between the sliders and guide rails on both sides of the counterweight. Because the sliders and guide rails are in direct contact and sliding for a long time, the interface friction resistance is large. Without lubrication, the contact surfaces wear rapidly, leading to increased energy consumption and affecting the continuous operation of the equipment. Utility Model Content

[0004] To address the aforementioned problems of high frictional resistance and easy wear in traditional fixed counterweights, this application provides a sliding counterweight mechanism.

[0005] The sliding counterweight mechanism provided in this application adopts the following technical solution:

[0006] A sliding counterweight mechanism includes a first mounting block, a slide rod fixedly connected to the bottom of the first mounting block, a second mounting block fixedly connected to the bottom of the slide rod, a sliding seat on the surface of the slide rod, a counterweight fixedly connected to the front of the sliding seat, multiple oil injection holes on the front of the first mounting block, an oil injection pipe fixedly connected to one end of each oil injection hole, an oil tank fixedly connected to one end of the oil injection pipe, a bottom block fixedly connected inside the oil tank, a downstream outlet in the middle of the bottom block, a plug attached to the inner wall of the downstream outlet, a round block fixedly connected to the top of the plug, a movable block fixedly connected to the top of the round block, a lead screw threadedly connected inside the movable block, and a motor fixedly connected to the top of the lead screw via a coupling.

[0007] Preferably, a protective cover is fixedly connected to the top of the oil tank, and a timer starter is fixedly connected to the top of the protective cover. The timer starter is electrically connected to the motor.

[0008] Preferably, the inner wall of the oil tank is provided with guide grooves on both sides, and a guide block is slidably connected inside the guide groove, and the guide block is fixedly connected to the movable block.

[0009] Preferably, the sliding seat has multiple sliding grooves inside, and a sliding sleeve is fixedly connected inside the sliding groove, and the sliding sleeve is slidably connected to the sliding rod.

[0010] Preferably, the oil injection hole is connected to the slide rod, and the surface of the oil tank is fixedly connected to an oil injection port.

[0011] Preferably, the inner wall of the sliding sleeve is provided with oil storage grooves, and the oil storage grooves are distributed in a ring array.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By setting up a timer starter and motor and other components, the delivery of lubricating oil can be controlled according to a preset time. This mechanism can deliver lubricating oil to the mating surfaces of the slide rod and the sliding seat periodically or as needed, effectively reducing the frictional resistance between the two, reducing wear on the contact surfaces, reducing operating energy consumption, and ensuring continuous and stable operation of the equipment.

[0014] 2. The sliding seat slides in contact with the slide rod through the sliding sleeve made of polytetrafluoroethylene composite material, which reduces the frictional resistance between the sliding seat and the slide rod and reduces wear. On the other hand, the oil storage grooves distributed in a ring array on the inner wall of the sliding sleeve can store lubricating oil, achieve continuous lubrication, and reduce the number of oiling times. In addition, the guide groove and guide block on the inner wall of the oil tank cooperate to ensure that the moving block moves in a straight line along the screw axis and avoids deviation and shaking.

[0021] The technical solutions of the embodiments of this application 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 this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1-5 This utility model provides a sliding counterweight mechanism, including a first mounting block 1, a slide rod 101 fixedly connected to the bottom of the first mounting block 1, a second mounting block 102 fixedly connected to the bottom of the slide rod 101, a sliding seat 2 provided on the surface of the slide rod 101, a counterweight block 201 fixedly connected to the front of the sliding seat 2, multiple oil injection holes 3 provided on the front of the first mounting block 1, an oil injection pipe 301 fixedly connected to one end of the oil injection hole 3, an oil tank 302 fixedly connected to one end of the oil injection pipe 301, a bottom block 402 fixedly connected inside the oil tank 302, a downstream outlet 403 provided in the middle of the bottom block 402, a plug 401 attached to the inner wall of the downstream outlet 403, a round block 4 fixedly connected to the top of the plug 401, a movable block 308 fixedly connected to the top of the round block 4, a lead screw 307 threadedly connected inside the movable block 308, and a motor 306 fixedly connected to the top of the lead screw 307 via a coupling.

[0023] When the sliding counterweight mechanism is in operation, the first mounting block 1 provides a fixed base for the top mounting of the entire mechanism. The slide rod 101 fixed at its bottom is the core guiding component for the sliding seat 2. The second mounting block 102 at the bottom of the slide rod 101 cooperates with the first mounting block 1 to fix both ends of the slide rod 101, ensuring the stability of the slide rod 101 during operation. The sliding seat 2 can slide on the surface of the slide rod 101. The counterweight block 201 fixed on the front of the sliding seat 2 adjusts its position by sliding the sliding seat 2 on the slide rod 101, thereby achieving the function of balancing the weight.

[0024] When lubrication is required on the mating surfaces of the slide rod 101 and the sliding seat 2, the motor 306 is started. The motor 306 drives the lead screw 307 to rotate via the coupling. Since the movable block 308 is threadedly connected to the lead screw 307, the rotation of the lead screw 307 is converted into the linear motion of the movable block 308. The movable block 308 drives the bottom fixed circular block 4 to move, and the circular block 4 in turn drives the plug block 401 to move, causing the plug block 401 to disengage from the lower outlet 403 in the middle of the bottom block 402. At this time, the lubricating oil in the oil tank 302 flows out through the lower outlet 403 and is transported to the oil injection hole 3 on the front of the first mounting block 1 via the oil injection pipe 301. The oil injection hole 3 guides the lubricating oil into the slide rod 101, thereby lubricating the mating surfaces of the slide rod 101 and the sliding seat 2.

[0025] The lubrication structure, consisting of oil injection hole 3, oil injection pipe 301, oil tank 302, bottom block 402, outlet 403, plug 401, round block 4, movable block 308, lead screw 307, and motor 306, can periodically or as needed deliver lubricating oil to the mating surfaces of slide rod 101 and sliding seat 2, reducing frictional resistance between them, reducing wear on contact surfaces, reducing operating energy consumption, and ensuring continuous and stable operation of the equipment.

[0026] In a preferred embodiment, a protective cover 304 is fixedly connected to the top of the oil tank 302, and a timer starter 305 is fixedly connected to the top of the protective cover 304. The timer starter 305 is electrically connected to the motor 306.

[0027] The protective cover 304 fixed to the top of the oil tank 302 protects the internal components such as the motor 306, preventing external dust and impurities from entering and affecting their operation. The timer starter 305 fixed to the top of the protective cover 304 is electrically connected to the motor 306. The operator can set the start time on the timer starter 305 according to the lubrication requirements of the mating surfaces of the slide rod 101 and the sliding seat 2. When the set time is reached, the timer starter 305 sends an electrical signal to the motor 306, controlling the motor 306 to start automatically. The motor 306 drives the lead screw 307 to rotate through the coupling, which in turn drives the movable block 308, the round block 4, and the plug block 401 to move, so that the lubricating oil in the oil tank 302 enters the slide rod 101 through the outlet 403, the oil filling pipe 301, and the oil filling hole 3 for lubrication.

[0028] The core of the timer starter 305 is to receive start and stop signals and switch the power supply circuit of the motor 306 through switching elements such as relays, contactors or thyristors to realize the start and stop of the motor 306. Its specific model is S2001A.

[0029] In a preferred embodiment, guide grooves 3091 are provided on both sides of the inner wall of the oil tank 302, and guide blocks 309 are slidably connected inside the guide grooves 3091. The guide blocks 309 are fixedly connected to the movable block 308.

[0030] When the motor 306 drives the lead screw 307 to rotate, causing the movable block 308 to move linearly along the lead screw 307, the guide blocks 309 fixed on both sides of the movable block 308 will slide synchronously within the guide grooves 3091 on both sides of the inner wall of the oil tank 302. The guide grooves 3091 restrict and guide the movement direction of the guide blocks 309, thereby restricting the movement direction of the movable block 308 through the guide blocks 309, ensuring that the movable block 308 can only move linearly along the axis of the lead screw 307, and preventing the movable block 308 from deviating or wobbling during movement.

[0031] In a preferred embodiment, the sliding seat 2 is provided with a plurality of sliding grooves 202 inside, and a sliding sleeve 203 is fixedly connected inside the sliding groove 202. The sliding sleeve 203 is slidably connected to the sliding rod 101.

[0032] The sliding sleeve 203 in this mechanism allows the sliding seat 2 to slide in contact with the sliding rod 101 through the sliding sleeve 203. The sliding sleeve 203 is made of polytetrafluoroethylene composite material, which can effectively reduce the frictional resistance between the sliding seat 2 and the sliding rod 101 and reduce the wear of both.

[0033] In a preferred embodiment, the oil filling hole 3 is connected to the slide rod 101, and the oil filling port 303 is fixedly connected to the surface of the oil tank 302.

[0034] The oil filling hole 3 is connected to the slide rod 101, ensuring that the lubricating oil delivered through the oil filling hole 3 can directly enter the slide rod 101 to provide lubrication for the mating surfaces of the slide rod 101 and the slide sleeve 203; the oil filling port 303 fixed on the surface of the oil tank 302 is used to replenish the lubricating oil in the oil tank 302. When the lubricating oil level in the oil tank 302 is low, the operator can add an appropriate amount of lubricating oil to the oil tank 302 through the oil filling port 303 to ensure that the lubrication system has a sufficient supply of lubricating oil.

[0035] In a preferred embodiment, the inner wall of the sliding sleeve 203 is provided with oil storage grooves, and the oil storage grooves are distributed in a ring array.

[0036] The oil storage groove on the inner wall of the sliding sleeve 203 can store lubricating oil, achieve continuous lubrication, extend the lubrication interval time, and reduce the number of oil injections.

[0037] The foregoing description of an exemplary embodiment of the sliding counterweight mechanism provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
