Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brick making equipment, in particular to an automatic hydraulic lifting device for a tail frame. Background Art
[0002] Brick making is the process of using stone powder, sand, slag, furnace slag, etc. as brick making materials and adding cement to make bricks. Brick making molds are needed to shape the bricks and complete the production of bricks.
[0003] Existing brick-making machines require adjusting the aggregate rack so that the feed cart on the rack is level with the upper mold frame to facilitate material distribution. Traditionally, this adjustment requires two people to simultaneously operate a jack to raise or lower the rack. While this method meets the requirements, the use of a jack is complex, requiring two people to operate simultaneously and prone to errors. Furthermore, the jack's limited travel limits significant adjustment limitations.
[0004] In order to solve this problem, the present invention is produced. Utility Model Content
[0005] Therefore, in order to solve the above problems, the present invention proposes an automatic hydraulic lifting device for a tailstock with a simple structure, simple operation and high adjustment accuracy.
[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is to provide an automatic hydraulic lifting device for a tailstock, comprising a frame, an aggregate rack arranged on the frame, and symmetrically arranged lifting cylinders, wherein the lifting cylinders are arranged on the frame, the extension rods of the lifting cylinders are arranged on the aggregate rack, and a guide device is provided on the frame.
[0007] A further improvement is that the guide device includes four guide columns, which are respectively arranged on the frame and located at both ends of the lifting cylinder. A guide sleeve is slidably provided on the guide column, and the guide sleeve is connected to the aggregate frame and linked to the aggregate frame.
[0008] A further improvement is that a positioning device is also provided on the frame.
[0009] A further improvement is that the positioning device includes an adjusting screw, one end of the adjusting screw is arranged on the frame, a positioning block is provided on the aggregate frame, the other end of the adjusting screw passes through the positioning block, and a first nut and a second nut are threadedly connected to the adjusting screw, the first nut and the upper end surface of the positioning block resist each other, and the second nut and the lower section of the positioning block resist each other.
[0010] A further improvement is that it also includes a third nut and a fourth nut respectively threadedly sleeved on the adjusting screw, the third nut resists one end of the frame, and the fourth nut resists the other end of the frame.
[0011] A further improvement is that a connecting plate is provided on the lifting cylinder, the lifting cylinder is passed through the frame, the connecting plate and the frame are connected by bolts to fix the lifting cylinder on the frame, the aggregate frame is provided with a hinge seat, and the extension rod of the lifting cylinder is hinged on the hinge seat.
[0012] The advantages and beneficial effects of the utility model are:
[0013] The structure is simple, the operation is simple and the adjustment precision is high. The two lifting cylinders work simultaneously to directly drive the aggregate rack to rise and fall, so that both ends of the aggregate rack rise or fall synchronously. The guide column and the guide sleeve cooperate to ensure that the aggregate rack can rise vertically stably when it rises, ensuring the adjustment precision and facilitating the operation of the staff. In addition, the long stroke of the lifting cylinder is more conducive to adjustment. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 This is a structural schematic diagram of the automatic hydraulic lifting device for the tailstock according to an embodiment of the present utility model. DETAILED DESCRIPTION
[0015] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.
[0016] like Figure 1 As shown, the tailstock automatic hydraulic lifting device includes a frame 1, an aggregate rack 2 mounted on the frame 1, symmetrically arranged lifting cylinders 3, and four guide posts 4. The lifting cylinders 3 are mounted on the frame 1, and the extension rods of the lifting cylinders 3 are mounted on the aggregate rack 2. The guide posts 4 are mounted on the frame 1 and at both ends of the lifting cylinders 3. Guide sleeves 5 are slidably mounted on the guide posts 4, and the guide sleeves 5 are connected to the aggregate rack 2 and interlock with the aggregate rack 2. During use, when the height of the aggregate rack 2 needs to be adjusted, the two lifting cylinders 3 operate simultaneously, and the extension rods of the lifting cylinders 3 extend, directly driving the aggregate rack 2 to rise or fall, so that both ends of the aggregate rack 2 rise or fall synchronously. The guide posts 4 cooperate with the guide sleeves 5 to ensure that the aggregate rack 2 can rise stably and vertically when it rises, ensuring the accuracy of the adjustment and facilitating the operation of the staff.
[0017] In order to protect the lifting cylinder 3, an adjusting screw 11 is also included. One end of the adjusting screw 11 is provided on the frame 1. The aggregate rack 2 is provided with a positioning block 6. The other end of the adjusting screw 11 passes through the positioning block 6. The adjusting screw 11 is threadedly connected to a first nut 7 and a second nut 8. The first nut 7 resists the upper end surface of the positioning block 6, and the second nut 8 resists the lower section of the positioning block 6. When the lifting cylinder 3 drives the aggregate rack 2 to a predetermined position, the first nut 7 and the second nut 8 rotate to resist the positioning block 6, thereby limiting the aggregate rack 2 and reducing the force on the lifting cylinder 3, thereby protecting the lifting oil and increasing the service life of the lifting cylinder 3.
[0018] In order to facilitate the installation of the adjusting screw 11, a third nut 9 and a fourth nut 10 are also included which are respectively threadedly sleeved on the adjusting screw 11. The third nut 9 resists one end of the frame 1, and the fourth nut 10 resists the other end of the frame 1.
[0019] In order to facilitate the installation of the lifting cylinder 3, a connecting plate 12 is provided on the lifting cylinder 3, and the lifting cylinder 3 is passed through the frame 1. The connecting plate 12 and the frame 1 are connected by bolts to fix the lifting cylinder 3 on the frame 1. A hinge seat 13 is provided on the aggregate frame 2, and the extension rod of the lifting cylinder 3 is hinged on the hinge seat 13.
[0020] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the present invention.
