Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic control, and particularly relates to a hydraulic control mechanism of a large-tonnage lifting platform for disassembling and assembling the furnace bottom of a chlorination furnace equipment in a process of preparing titanium tetrachloride by a chlorination method. Background Art

[0002] In the production process of titanium tetrachloride by the chlorination method, the process method is to adopt boiling chlorination method, that is, chlorine gas, titanium-rich materials and petroleum coke are reacted in a chlorination furnace to obtain titanium tetrachloride. During this period, the bottom of the main equipment chlorination furnace is disassembled and assembled frequently. Since the bottom of the furnace is heavy and the high-temperature chemical materials in the furnace are piled up on the bottom of the furnace, there are many safety risk factors during disassembly and assembly, so the use of lifting platform operation is widely used in this working condition.

[0003] In the prior art, the hydraulic rod lifting platform cannot meet the large tonnage load, and the platform cannot rotate and cannot be accurately aligned; the prior art adopts a single-stage single-acting oil cylinder lifting platform. Due to the insufficient lifting stroke, multiple heavy jacks are arranged on the platform in a circumferential direction to cooperate with manual operation. There are the following problems in operation: when the material temperature has not dropped, it is difficult for personnel to approach normally, and the stability and synchronization of operating multiple jacks are poor, and they are easy to deflect. When deflected, it will cause jamming during the lifting and lowering process, and the furnace body equipment will be damaged to varying degrees; the top platform cannot rotate, and it is difficult to adjust when aligning the screw holes on the circumference of the furnace bottom flange; and the inertial impact force is large when lifting the newly installed furnace bottom to the platform, causing damage to the equipment; because it is a single-acting oil cylinder, it only relies on its own weight during the return stroke. When intermittent jamming occurs during operation, it will suddenly and rapidly decline, the operation stability is poor, and there is a risk of safety hazards. Summary of the invention

[0004] The present invention aims to solve the defects and problems existing in the prior art, such as poor lifting stability, difficulty in adjusting the alignment during installation, and short service life of the hydraulic cylinder. A hydraulic lifting mechanism is provided, which has good lifting stability, long service life, a lifting stroke that meets the requirements, and can carry a large tonnage.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a rail-type multi-stage double-acting hydraulic cylinder lifting platform vehicle, circumferentially arranged balls are arranged between the rotating platform and the cylinder platform, a frame is arranged below the cylinder platform, and a high-temperature dustproof cloth cover is installed in the gap between the cylinder platform and the frame; The travel drive device is installed and fixed in the frame and connected with the travel wheel through a sprocket drive; The double-acting cylinder is fixed in the frame and directly connected to the cylinder platform; The two ends of the oil pipe are connected to the double-acting oil cylinder and the hydraulic assembly respectively, and the oil tank is directly connected in series with the hydraulic assembly; The running wheels are embedded in the rails.

[0006] The beneficial effects of adopting the above technical solution are: 1. The present invention solves the defects and problems existing in the prior art, such as poor lifting stability, difficulty in adjusting the alignment during installation, and short service life of the hydraulic cylinder.

[0007] 2. The present invention realizes a hydraulic lifting mechanism with good lifting stability, long service life, lifting stroke that meets the requirements, and the ability to carry large tonnage.

[0008] 3. The present invention has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is further described in detail below in conjunction with the accompanying drawings, but it should not be understood that the scope of the subject matter described in the present invention is limited to the following embodiments. Without departing from the above-mentioned technical ideas of the present invention, various modifications, substitutions and changes made according to the common technical knowledge and customary means in the field are included in the scope of the present invention.

[0012] A rail-type multi-stage double-acting hydraulic cylinder lifting platform vehicle, wherein circumferentially arranged balls 2 are provided between a rotating platform 1 and a cylinder platform 3, a frame 6 is provided below the cylinder platform 3, a high-temperature dustproof cloth cover 4 is installed in the gap between the cylinder platform 3 and the frame 6, a travel drive device 5 is installed and fixed in the frame 6, and is connected to a travel wheel 11 through a sprocket transmission, a double-acting cylinder 7 is fixed in the frame 6, and is directly connected to the cylinder platform 3, two ends of an oil pipe 8 are respectively connected to the double-acting cylinder 7 and a hydraulic assembly 9, an oil tank 10 is directly connected in series with the hydraulic assembly 9, and a travel wheel 11 (front and rear wheels) is embedded in a track 12.

[0013] The travel of the lift truck and the lifting of the cylinder are both operated by a handheld remote control: Driven by the motor, the hydraulic oil in the oil tank 10 is pumped into the hydraulic cylinder 7 through the hydraulic bearing 9 (including electromagnetic reversing valve, superimposed throttle valve, hydraulic control valve and other components), so as to realize the lifting and lowering of the rotating platform 1 and the cylinder platform 3 by the cylinder, thereby completing the lifting and lowering process; the double-acting multi-stage hydraulic cylinder 7 is provided with two hydraulic chambers (rod chamber and rodless chamber). When rising, the hydraulic oil is pumped into the rodless chamber, and the rod chamber returns oil; when falling, the rod chamber is filled with oil, and the rodless chamber returns oil. The lifting and lowering are realized by oil pressure, and the operation process is safe and stable; the upper rotating platform 1 can rotate arbitrarily in the circumference under the action of the ball 2, which is convenient for the alignment adjustment of the flange screw hole; the high-temperature resistant dustproof cloth cover 4 rises and falls synchronously with the hydraulic cylinder during operation, which can effectively isolate the material from entering the frame 6, and prevent the high-temperature material from directly contacting the cylinder body and accessories such as the oil pipe, and play a safety protection role; the travel drive device 5 of the lifting vehicle drives the travel wheel 11 forward and backward along the track 12 through the reduction motor.

[0014] The device designed by the present invention has a strong load-bearing capacity (under current working conditions, the designed load-bearing capacity is 80t), stable operation, and a long service life, and can achieve efficient and reliable performance under various working conditions such as high temperature and corrosive environment.
