Abstract

The utility model discloses a large power-driven lead screw pressure test machine which comprises a base with a lower compression plate, a top beam which is fixed by a bracket, a lead screw which is in threaded connection with the top beam, a lifting driving mechanism and a distribution box, wherein an upper compression pate is arranged at the lowest end of the lead screw; the peak load capacities of the upper compression plate and the lower compression plate are both3000kN. The pressure test machine is characterized in that the lifting driving mechanism is a speed reducer, a gear box is arranged in the top beam; a gear which is in threaded connection with lead screw is arranged in the gear box; the gear is limited by an upper limiting plate and a lower limiting plate; the gear is connected with the speed reducer by a chain so as to form a transmission mechanism for the lead screw. The large power-driven lead screw pressure test machine can be used for pressure test machines with load capacity being 3000kN and more. According to the machine, the power-driven type driving structure can replace the original manual adjusting structure, so that a worker can operate the machine without being close to the machine, and the accident danger can be avoided.

Description

A kind of Large Electric leading screw pressure testing machine
Technical field
The utility model belongs to digital pressure testing machine technical field, relates to a kind of pressure testing machine of large-scale electric screw-type, and peak load is 3000Kn.
Background technology
Pressure testing machine is mainly used in testing the mechanical performance index of normal concrete.Being applicable to detect the experiment of agent on crack resistance of concrete pressure intensity, is the necessary equipment of building, building materials, highway, bridge and Aerodrome construction unit.Be 200920350246.6 utility model patent referring to the patent No., present pressure testing machine is manual loading, regulates the height of top board on structure by the form of hand wheel rotating leading screw, and then the maximum load-carrying capacity of test sample.The mode of this manual adjustments in use is very difficult to hold the test dynamics, especially surpasses more than 2000kN, when manually regulating pressure by the people, has been difficult to rotate handwheel, causes test findings undesirable.And easily the operator is caused unnecessary injury.
The utility model content
The purpose of this utility model is in order to improve the operability to pressure testing machine, to avoid the operator to come to harm, having designed a kind of pressure testing machine of electric screw-type.
The technical solution of the utility model is, a kind of Large Electric leading screw pressure testing machine, comprise base with lower platen, by the fixing back timber of support, the leading screw, lift drive mechanism and the panel box that are threaded with back timber formation, top board is arranged on leading screw bottom, wherein the peak load of top board and lower platen is 3000kN, and key is: described lift drive mechanism is reductor; Be provided with gear case in back timber, be provided with the gear that is connected with threads of lead screw in gear case, gear is spacing by upper limit plate and lower limiting board, and gear is connected to form the gear train of leading screw by chain and reductor.
Be provided with lubricant layer between described gear and upper limit plate and lower limiting board.
Described top board and lower platen are rectangle, are of a size of 320 * 330mm.
The utility model be specially adapted to load at 3000kN the pressure testing machine more than even.By substituted original manual adjustments structure with DYN dynamic drives structure, make workman's device of need not disembarking very closely just can operate machines, keep away the danger that meets accident.In addition, by DYN dynamic loading mode, make the Output pressure of pressure testing machine very linear, satisfy user's test request, meet the standard of GB/T50081-2002.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram of Fig. 1 middle gear box structure.
1 represents back timber, and 2 represent gear case, and 2-1 represents gear, and 2-2 represents the upper limit plate, and 2-3 represents lower limiting board, and 3 represent support, and 4 represent leading screw, and 5 represent base, and 6 represent top board, and 7 represent lower platen, and 8 represent oil cylinder.
Embodiment
A kind of Large Electric leading screw pressure testing machine, comprise base 5 with lower platen 7, by the fixing back timber 1 of support 3, the leading screw 4, lift drive mechanism and the panel box that are threaded with back timber 1 formation, top board 6 is arranged on leading screw 4 bottom, wherein top board 6 is 3000kN with the peak load of lower platen 7, and key is: described lift drive mechanism is reductor; Be provided with gear case 2 in back timber 1, be provided with the gear 2-1 that is threaded with leading screw 4 in gear case 2, gear 2-1 is spacing by upper limit plate 2-2 and lower limiting board 2-3, and gear 2-1 is connected to form the gear train of leading screw 4 by chain and reductor.
Be provided with lubricant layer between described gear 2-1 and upper limit plate 2-2 and lower limiting board 2-3.
Described top board 6 is rectangle with lower platen 7, is of a size of 320 * 330mm.
The utility model in the specific implementation, drive motor is fixed on a side of testing machine, is connected to form gear train by the gear 2-1 in chain and gear case 2.Gear 2-1 inner ring is threaded, as long as gear 2-1 rotates, leading screw 4 can rotate lifting thereupon.In order to make gear 2-1 constant in short transverse, ad hoc have upper limit plate 2-2 and lower limiting board 2-3, and be provided with lubricant layer between upper limit plate 2-2 and lower limiting board 2-3 and gear 2-1, avoids wearing and tearing to cause scrapping.The utility model passes to oil cylinder 8 by the pressure of carrying on lower platen 7, and then perception testing machine applied pressure.The utility model has been by having substituted original manual adjustments structure with DYN dynamic drives structure, make workman's device of need not disembarking very closely just can operate machines, and keeps away the danger that meets accident.In addition, by DYN dynamic loading mode, make the Output pressure of pressure testing machine very linear, satisfy user's test request, meet the standard of GB/T50081-2002.
