Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic car jacking machine technology, specifically a hydraulic car jacking machine. Background Technology
[0002] The hydraulic jack is a key piece of equipment used for pushing kiln cars in the kiln production process. Its core function is to smoothly and uniformly send the kiln cars into the drying kiln or firing kiln, realizing the automated and continuous operation of kiln cars entering and leaving the kiln. The hydraulic jack consists of a hydraulic station, oil cylinders, a frame, and a jacking head. The hydraulic station provides power to the oil cylinders to push the jacking head to send the kiln cars into the kiln. To ensure the stability of the jacking process, the frame and the jacking head are connected and guided by slide rails and guide rails.
[0003] However, in kiln production scenarios, hydraulic jacking machines are exposed to harsh environments of high temperature and high dust for a long time. During the process of loading and transporting brick blanks, due to the characteristics of the brick blanks themselves and factors such as vibration and collision during the transportation process, it is inevitable that fragments will appear. These detached particles are easily scattered into the gap between the slide rail and the guide rail due to the vibration of the equipment, resulting in insufficient smooth sliding or even jamming between the slide rail and the guide rail, which affects the use of the jacking machine. Therefore, a hydraulic jacking machine is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic jacking machine, which has the advantages of being less prone to jamming and having high operational stability. It solves the problem that existing hydraulic jacking machines rely on slide rails and guide rails for guidance, but in kiln production, they are in a high-temperature and high-dust environment for a long time. When the kiln car is transporting brick blanks, debris falls off and particles scatter into the gap between the slide rail and guide rail, causing poor sliding or even jamming, which affects the performance.
[0005] To achieve the aforementioned goals of being less prone to jamming and having high operational stability, this utility model provides the following technical solution: a hydraulic car jack, comprising a support frame and a jacking plate, wherein a connecting guide assembly is provided between the support frame and the jacking plate;
[0006] The connecting guide assembly includes a guide rail fixedly installed inside the support frame. Two sets of guide wheels are slidably installed inside the guide rail. A connecting plate is fixedly installed on the surface of the guide wheel set, passing through one side of the guide rail. A base plate is fixedly installed at the bottom of the connecting plate. A movable support wheel that contacts the bottom of the inner side of the support frame is rotatably installed on the lower surface of the base plate. A fixed plate is fixedly installed on the upper surface of the base plate. A push plate is fixedly installed on the top of the fixed plate. A driving assembly is provided between the support frame and the fixed plate. A cleaning assembly for cleaning the inside of the support frame is provided on the surface of the base plate.
[0007] Furthermore, the cross-sectional shape of the support frame is U-shaped, and the number of guide rails is two, which are symmetrically distributed on opposite sides of the inner surface of the support frame.
[0008] Furthermore, the guide rail has a hollow interior structure, and a strip-shaped hole communicating with the interior of the guide rail is provided on the bottom surface of the guide rail. The connecting plate extends to the lower surface of the guide rail through the strip-shaped hole.
[0009] Furthermore, the guide wheel assembly consists of a connecting shaft and two pulleys. The two pulleys are rotatably mounted on both ends of the connecting shaft, and the connecting plate is fixedly mounted on the surface of the connecting shaft. The pulleys are adapted to the interior of the guide rail, and the two pulleys are distributed on both sides of the strip hole.
[0010] Furthermore, the drive assembly includes a mounting plate fixedly installed on one side of the support frame and guide rail, and a hydraulic cylinder is fixedly installed on the surface of the mounting plate, with the telescopic end of the hydraulic cylinder fixedly connected to the fixed plate.
[0011] Furthermore, a baffle is fixedly installed on the surface of the guide rail away from the mounting plate.
[0012] Furthermore, the cleaning assembly includes a strip connecting plate rotatably mounted on the surface opposite to the base plate, a cleaning plate fixedly mounted on the surface of the strip connecting plate away from the base plate, and a counterweight fixedly mounted on the surface of the cleaning plate.
[0013] Furthermore, the side of the cleaning plate away from the bottom plate contacts the inner bottom surface of the support frame, and the side of the cleaning plate that contacts the inner bottom surface of the support frame is an inclined surface.
[0014] Compared with the prior art, the present invention provides a hydraulic car jack, which has the following advantages:
[0015] This hydraulic top-mounting machine, through its built-in guide wheel assembly that rolls within the cavity of the guide rail, ensures that the openings on the guide rail surface face the bottom of the support frame. This prevents contaminants such as debris and particles falling from the kiln car from directly entering the gap between the pulleys and the guide rail, thus guaranteeing the smooth operation of the top-mounting plate. Simultaneously, when the base plate drives the top-mounting plate in reciprocating motion, the counterweight ensures that the inclined end of the cleaning plate remains in contact with the inner bottom surface of the support frame, creating relative sliding. This effectively removes debris and particles scattered at the bottom of the support frame, maintaining the cleanliness of the support frame's interior, reducing debris interference with equipment operation, and improving the stability of equipment operation.

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.
[0023] Please see Figure 1-5 This embodiment of a hydraulic jacking machine includes a support frame 1 and a jacking plate 2. A connecting guide assembly 3 is provided between the support frame 1 and the jacking plate 2. The connecting guide assembly 3 includes a guide rail 31 fixedly installed inside the support frame 1. Two sets of guide wheels 32 are slidably installed inside the guide rail 31. A connecting plate 33 is fixedly installed on the surface of the guide wheel set 32, passing through one side of the guide rail 31. A base plate 34 is fixedly installed at the bottom of the connecting plate 33. A movable support wheel 35 that contacts the bottom of the inner side of the support frame 1 is rotatably installed on the lower surface of the base plate 34. A fixing plate 36 is fixedly installed on the upper surface of the base plate 34. The jacking plate 2 is fixedly installed on the top of the fixing plate 36. A driving assembly 4 is provided between the support frame 1 and the fixing plate 36. A cleaning assembly 5 for cleaning the inside of the support frame 1 is provided on the surface of the base plate 34.
[0024] In this embodiment, the cross-sectional shape of the support frame 1 is U-shaped, and the number of guide rails 31 is two and they are symmetrically distributed on opposite sides of the inner surface of the support frame 1.
[0025] In this embodiment, the interior of the guide rail 31 is a hollow structure, and a strip hole 6 communicating with the interior of the guide rail 31 is provided on the bottom surface of the guide rail 31. The connecting plate 33 extends to the lower surface of the guide rail 31 through the strip hole 6.
[0026] In this embodiment, the guide wheel assembly 32 consists of a connecting shaft 321 and two pulleys 322. The two pulleys 322 are rotatably mounted on both ends of the connecting shaft 321, and the connecting plate 33 is fixedly mounted on the surface of the connecting shaft 321. The pulleys 322 are adapted to the inside of the guide rail 31, and the two pulleys 322 are distributed on both sides of the strip hole 6.
[0027] In this embodiment, the drive assembly 4 includes a mounting plate 41 fixedly installed on one side of the support frame 1 and the guide rail 31. A hydraulic cylinder 42 is fixedly installed on the surface of the mounting plate 41, and the telescopic end of the hydraulic cylinder 42 is fixedly connected to the fixed plate 36.
[0028] In this embodiment, a baffle 7 is fixedly installed on the surface of the guide rail 31 away from the mounting plate 41 to prevent the guide wheel assembly 32 from falling out of the guide rail 31.
[0029] In this embodiment, the cleaning component 5 includes a strip connecting plate 51 rotatably mounted on the surface opposite to the base plate 34, a cleaning plate 52 fixedly mounted on the surface of the strip connecting plate 51 away from the base plate 34, and a counterweight 53 fixedly mounted on the surface of the cleaning plate 52. The cleaning component 5 facilitates the cleaning of debris inside the support frame 1.
[0030] In this embodiment, the side of the cleaning plate 52 away from the bottom plate 34 is in contact with the inner bottom surface of the support frame 1. The side of the cleaning plate 52 that is in contact with the inner bottom surface of the support frame 1 is a slope, which is conducive to better contact between the cleaning plate 52 and the inner bottom surface of the support frame 1.
[0031] It should be noted that in this embodiment, the hydraulic cylinder 42 is powered and controlled by an external hydraulic station, and the hydraulic station and the hydraulic cylinder 42 are connected by hydraulic oil pipes.
[0032] The working principle of the above embodiments is as follows:
[0033] When the hydraulic system is started, the extension end of the hydraulic cylinder 42 begins to move in a straight line, which in turn drives other components connected to the fixed plate 36 to move together. During the pushing process, the pulley 322 rolls inside the guide rail 31, guiding the connecting plate 33 to move in a straight line along the direction of the guide rail 31. At the same time, the base plate 34 is fixedly installed at the bottom of the connecting plate 33. The lower surface of the base plate 34 is rotatably mounted with a movable support wheel 35, which contacts the bottom inner side of the support frame 1. As the push plate 2 moves, the moving support wheel 35 rolls accordingly, providing additional support for the entire structure, sharing some of the weight, and reducing the force on the guide wheel assembly 32. The push plate 2 is fixedly installed on the top of the fixed plate 36 and moves with the movement of the fixed plate 36 to push the kiln car. During the movement of the push plate 2, when the guide wheel assembly 32 approaches the end of the guide rail 31, the baffle 7 can act as a block to prevent the guide wheel assembly 32 or other components from exceeding the travel range of the guide rail 31 due to unexpected circumstances, avoiding equipment damage or safety accidents, and ensuring the personal safety of operators and the normal operation of the equipment. During the movement of the push plate 2, the bottom plate 34 drives the cleaning assembly 5 to move together. The inclined design of the cleaning plate 52 allows it to better fit the inner bottom surface of the support frame 1, cleaning out the debris particles scattered at the bottom of the support frame 1, keeping the inside of the support frame 1 clean, and reducing the interference of debris on the fit gap between the guide wheel assembly 32 and the guide rail 31, as well as the contact surface between the moving support wheel 35 and the inner bottom of the support frame 1.
