Abstract
The utility model provides a tray assembly for increasing the working height of a lifting device, which comprises an elongated support and a tray, wherein the elongated support comprises a connecting screw rod, a base, a heightening cylinder and a tray seat which are matched with the tray seat thread structure of the lifting device, the upper end and the lower end of the heightening cylinder are respectively welded and fixed with the tray seat and the base, the bottom of the base is welded and fixed with the connecting screw rod, and the tray is in threaded connection with the tray seat through a tray screw; the lifting device is compact and simple in structure and convenient to operate, and can effectively solve the inconvenience caused by the fact that the rated working height of the lifting device cannot meet the operation requirement.
Description
Technical Field
The utility model relates to a lifting devices technical field indicates a tray subassembly for increasing lifting devices operating height very much.
Background
When electromechanical equipment assembly, automobile maintenance and other work are carried out daily, lifting devices such as a jack, a lifting machine, a press machine and the like are commonly used for lifting a heavy object to a certain height, and then the next operation can be carried out. However, the lifting devices in the prior art are designed to have a rated working height, so when a heavy object needs to be lifted to exceed the rated working height of the lifting device, inconvenience is caused to the assembly of electromechanical equipment, the maintenance of automobiles and other work, and even the work cannot be carried out.
Therefore, the prior art has a larger improvement space.
SUMMERY OF THE UTILITY MODEL
The utility model aims at remedying the not enough of prior art, provide a tray assembly for increasing lifting device operating height, its simple structure, convenient operation can effectively solve because lifting device's rated working height can't reach the inconvenience that the operation requirement leads to.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
a tray subassembly for increasing lifting device working height, including adding long support, tray, add long support include with lifting device's tray seat helicitic texture adaptation connecting screw, base, increase a section of thick bamboo, tray seat, the upper and lower end difference welded fastening who increases a section of thick bamboo tray seat, base, the bottom welded fastening of base connecting screw, the tray passes through tray screw and tray seat threaded connection.
According to the scheme, two fixing holes are symmetrically formed in the wall of the heightening barrel, and circular shafts penetrate through the two fixing holes. The force arm of the lengthened support during rotation can be increased through the arrangement of the round shaft, so that the connecting screw rod can rotate more quickly and more conveniently, labor is saved, and the installation effect is improved.
According to the scheme, the mounting groove has been seted up to the tray upper surface, inlay in the mounting groove and be connected with the tray pad, the tray pad is made by flexible material. Through the structure, the scratch and abrasion caused by direct contact of the heavy object and the tray are prevented.
The beneficial effects of the utility model reside in that:
the utility model is provided with the lengthened support, and the working height of the lifting device can be quickly and conveniently increased by fixedly connecting the connecting screw rod with the tray seat of the lifting device; the fixed mounting of the connecting screw rod and the lifting device can be realized more quickly and more laborsavingly by arranging the fixed hole and the round shaft on the heightening cylinder; the lifting device has the advantages of compact and simple integral structure and convenient operation, and can effectively solve the inconvenience caused by the fact that the rated working height of the lifting device cannot meet the operation requirement.
Drawings
FIG. 1 is a schematic structural view of a tray assembly for increasing the working height of a lifting device according to the present invention;
fig. 2 is a cross-sectional view of a tray assembly for increasing the working height of a lifting device according to the present invention.
In the figure: 1. lengthening the support; 2. connecting a screw rod; 3. a base; 4. a heightening cylinder; 5. a tray seat; 6. a tray; 7. a tray screw; 8. a tray pad; 9. a fixing hole; 10. a circular shaft.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1, a tray subassembly for increasing lifting devices working height, including extension support 1, tray 6, extension support 1 includes with lifting devices's tray seat screw structure adaptation connecting screw 2, base 3, increase a section of thick bamboo 4, tray seat 5, the upper and lower end difference welded fastening who increases a section of thick bamboo 4 tray seat 5, base 3, the bottom welded fastening of base 3 connecting screw 2, tray 6 passes through tray screw 7 and tray seat 5 threaded connection.
Furthermore, two fixing holes 9 are symmetrically formed in the wall of the heightening barrel 4, and a circular shaft 10 penetrates through the two fixing holes 9. The force arm of the lengthened support 1 during rotation can be increased through the arrangement of the round shaft, so that the connecting screw rod 2 can rotate more quickly and more laborsavingly, and the installation effect is improved.
Further, a mounting groove is formed in the upper surface of the tray 6, a tray pad 8 is connected to the mounting groove in an embedded mode, and the tray pad 8 is made of flexible materials. Through the structure, the scraping abrasion caused by the direct contact of the heavy object and the tray 6 is prevented.
Use during a tray subassembly for increase lifting device operating height, earlier place connecting screw 2 on the helicitic texture of lifting device tray seat, thereby make through holding the round axle and make extension support 1 rotate can be fast with connecting screw 2 and lifting device's tray seat fixed connection, make the utility model discloses a tray subassembly and lifting device fixed connection to can realize increasing lifting device's operating height, its simple structure, convenient operation can effectively solve because lifting device's rated duty altitude can't reach the operating requirement and the inconvenience that leads to.
The above is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the claims of the present invention.
