Abstract

The utility model discloses an assembly adjustment tool for a tyre crane box type saddle beam, which aims to overcome the disadvantages that in the prior art, during the assembly of the tyre crane saddle beam, the assembly and disassembly of a tool for adjusting web plates can affect the quality of the whole saddle beam, and has high manufacturing cost, large labor intensity, and more pollution to the environment. An outer frame which can enclose the web plates and, an upper wing plate and a lower wing plate of the tyre crane box beam is provided with nuts with central lines perpendicular to the web plates, and stretching screws facing toward the web plates are screwed in the nuts. The adjustment to the web plates of the box beam is realized through a detachable mechanical connection mode to arrange the stretching screws which can be imposed with external force on the outer frame but not welded on the web plates, so the web plates can not affect the quality of the box beam due to high temperature, the plate adjustment does not need other auxiliary equipment, has small labor intensity, does not consume welding rods, oxygen, acetylene and electricity, and has low manufacturing cost, and the assembly adjustment tool can not produce pollution and radiation and can not cause harm to a human body.

Description

Tyre crane box-shaped saddle beam assembling adjustment instrument

Technical field

The utility model belongs to instrument, specifically a kind ofly assembles the instrument that tyre crane box-shaped saddle beam is used.

Background technology

Tyre crane saddle beam is that the box-girder steel construction is shown in the dotted portion among Fig. 1, comprise the lower wing plate 4.2 that lies in ground, the upper flange 4.3 at top, space certain distance between the last lower wing plate, one group of parallel baffle 4.1 using as reinforcement, and be fixed between the upper and lower wing plate, with dividing plate 4.1 terminations two coxostermums 3 connected vertically, form the tyre crane saddle beam of box structure jointly.During assembling saddle beam, earlier with lower wing plate and dividing plate and two coxostermums integrally welded after, again with the upper flange Combination Welding together.

Because the volume of saddle beam is very big, normal length reaches more than ten meter, last lower wing plate, dividing plate and two coxostermums are also all bigger, the web of box-shaped saddle beam both sides can produce deformation of unevenness when welding with the two ends of dividing plate, cause the top edge of web and upper flange to fashionable, it can not overlap zygonema, causes the involutory welding difficulty of web and upper flange.Therefore the relative position between them must consistently better weld fixing.

After the welding of two coxostermums and dividing plate, must apply external force to the web after the distortion and carry out the return adjustment, and then with the involutory welding in upper flange lower end.The method of adjusting at present two coxostermums is: will with about revolve the screw mandrel of screw thread, the screw that is screwed into the band left and right sides, two ends medial rotation screw thread respectively is interior as the adjustment instrument, during use, with be screwed on the screw about revolve that the screw mandrel two ends are oblique takes above the lower wing plate that is placed between two dividing plates and the top of web, and with about revolve the screw mandrel two ends and weld fixing respectively, turn the screw mandrel that revolves about the screw tractive of band left and right sides medial rotation screw thread, adjust the deformation of unevenness of web.After treating web adjusted, also to separate carrying out gas cutting with cutting torch with the left and right sides screw mandrel that adjusts instrument and lower wing plate and web.

Because above-mentioned method of welding the adjustment instrument on web makes web be subjected to high-temperature heat treatment, has influence on the quality of parent material of web, thereby has influence on the mechanical property of material, and then have influence on the quality of whole saddle beam; Simultaneously after finishing the web adjustment, also the adjustment instrument to be cut off, and the light of polishing of the welding position after cutting off handled, to expend so a large amount of welding rods, oxygen, acetylene and, also to use a series of auxiliary equipment such as abrasive machine, make the manufacturing cost height of tyre crane saddle beam, labour intensity is big and loaded down with trivial details; Moreover installation and dismounting adjustment instrument can increase the pollution and the radiation of gas, have strengthened the harm to human body.

The utility model content

Technical problem to be solved in the utility model is, overcome prior art in assembling tyre crane saddle beam process, adorn, tear open and adjust web can have influence on whole saddle beam with instrument quality, and manufacturing cost height, labour intensity are big, and the shortcoming that increases environmental pollution, a kind of tyre crane box-shaped saddle beam assembling adjustment instrument is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: can enclose on the outside framework of the web of tyre crane box-girder and last lower wing plate, be positioned at the outside of two coxostermums, be provided with the nut of its center line, be screwed with the adjustment screw rod of subtend web in the nut perpendicular to web.

The utility model also has following technical characterictic:

The described circle at the web of tyre crane box-girder and the outside framework of last lower wing plate is at " U " shape frame lower end that can ride over outside the box-girder, and lower plate is installed;

Be positioned at an end of nearly web at described adjustment screw rod, be fixed with the decorative pearl on top of an official cap.

Advantage of the present utility model and good effect are, because adjustment to the box-girder web, be with enclosing in the web of tyre crane box-girder and the outside framework of wing plate, mode with dismountable mechanical connection, the adjustment screw rod that can add external force adjustment web is installed on the outside framework, do not need to be welded on the web, thereby web can not be subjected to high-temperature process, not influence the quality of box-girder; After finishing the web adjustment, unload the adjustment instrument and get final product simultaneously, saved time, the auxiliary equipment of grinding process, labour intensity is little; Do not expend welding rod, oxygen, acetylene and electricity, reduced the manufacturing cost of tyre crane box-girder, dismounting is simultaneously adjusted instrument and is not produced pollution and radiation, can not work the mischief to human body.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, shown in the dotted portion is box-girder 4 structures of tyre crane, comprise the lower wing plate 4.2 that lies in ground, the upper flange 4.3 at top, space certain distance, work are strengthened one group of parallel baffle 4.1 of usefulness between the last lower wing plate, and be fixed between the upper and lower wing plate, with dividing plate 4.1 terminations two coxostermums 3 connected vertically, form box structure jointly.Can enclose on the web 3 and last lower wing plate outside framework 1 of tyre crane box-girder 4, be positioned at the outside of two coxostermums 3, be provided with the nut 1.2 of its center line, be screwed with in the nut 1.2 and adjust screw rod 2 (referring to Fig. 4) perpendicular to web 3.

The described circle at the web 3 of tyre crane box-girder 4 and the outside framework of last lower wing plate, be can ride over box-girder 4 fall " U " shape frame 1.1, be positioned on the lower end below the lower wing plate 4.2 of box ellbeam 4, lower plate 1.3 (referring to Fig. 2, Fig. 3) is installed, the installation of lower plate 1.3, be to fall two lower ends of " U " shape frame 1.1 to exist, be inserted in the hole corresponding on the lower plate 1.3, make whole outside framework 1 circle on the outside of box-girder 4 outsides.

In order to strengthen the pressure of adjusting 2 pairs of webs 3 of screw rod, increase the adjustment dynamics, the termination that is positioned at web 3 at described adjustment screw rod 2 is fixed with the decorative pearl on top of an official cap 2.1, is equipped with at the other end of adjusting screw rod 2 and adjusts with handwheel 2.2 (referring to Fig. 4).
