Abstract

The invention discloses a welding clamp for a support cylinder of a harbor crane and belongs to the technical field of shipbuilding. The welding clamp comprises a base plate, a pair of support racks disposed on the base plate and a roller sleeving between the two support racks. Each support rack comprises a support base plate and two support plates which are oppositely vertically disposed on the support base plate. Slide grooves allowing the support racks to slide in are formed in the base plate along the length direction. A hydraulic motor for driving the roller to rotate is disposed on the outer side of one of the support plates. By the welding clamp, the problems that the support cylinder is difficult to turn over, many in tools, high in building cost and inconvenient in management are solved.

Description

Portal crane supporting cylinder weld jig
Technical field
The present invention relates to shipbuilding technical field, especially a kind of welding tooling for portal crane supporting cylinder.
Background technology
In shipping industry, usually the cylindrical portion of two sections to be welded as to a supporting cylinder for portal crane, the supporting cylinder welding of existing portal crane is used a kind of as Fig. 3, welding tooling shown in Fig. 4, this welding tooling includes roller 16, base plate 15 and 2 bracing frames 11 that are fixed on two ends on base plate 15, bracing frame 11 includes support baseboard 11-2 and is vertically to two gripper shoe 11-1 that are oppositely arranged on support baseboard 11-2, roller 16 is installed on respectively between gripper shoe 11-1 by its mandrel 12, mandrel 12 two ends are respectively installed with sheath 13, 16 liang of outsides of roller are respectively installed with sheath 14.This kind of frock exists: 1, because roller does not have power drive, in the time being soldered to the bottom of cylinder, will be manually supporting cylinder reverse welding or welder be lain under supporting cylinder supporting cylinder is welded in the overhead position, artificial upset supporting cylinder, labour intensity is large, inefficiency, and to cylinder weld in the overhead position not only operating difficulties and potential safety hazard high; 2, because pulley is fixedly connected on base plate, in the time welding the cylinder of different size, need to produce the frock of various different sizes, the quantity of frock is many, and frock construction cost is high, the problem of inconvenience management.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of portal crane supporting cylinder weld jig, this portal crane supporting cylinder weld jig can solve supporting cylinder upset difficulty and the many construction cost of frock quantity high, the problem that inconvenience is managed.
In order to address the above problem, the technical solution adopted in the present invention is: this portal crane supporting cylinder weld jig, include base plate, be arranged at the pair of supporting on this base plate and be sleeved on the roller between support frame as described above, support frame as described above includes support baseboard and relative 2 gripper shoes that are vertically on support baseboard, on described base plate, offer along its length the chute sliding for bracing frame, the hydraulic motor that the arranged outside of described gripper shoe has driving rolls to rotate.
In technique scheme, technical scheme can also be more specifically: described roller is to be installed between described gripper shoe by its mandrel, two outsides of described roller are set with the second sheath, described mandrel is set with the first sheath near described gripper shoe end, and the other end of described mandrel is connected with the output shaft of described hydraulic motor by shaft joint; The hydraulic fluid port of described hydraulic motor is connected with the hydraulic fluid port of pumping plant.
Further: described base plate and described support baseboard are bolted; Under described support baseboard, be fixedly connected with the slide block sliding in chute.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to offering along its length the chute sliding for bracing frame on base plate, base plate and support baseboard are threaded connection; In the time of the supporting cylinder of welding different size, can unclamp screw thread by base plate between two end supports frame distance adjustment weld to correct position, can adapt to the cylinder of different size, contour structures is simple and practical, frock construction cost is low, convenient management.
2, the hydraulic motor that has driving rolls to rotate due to the arranged outside of gripper shoe, the output shaft of hydraulic motor is fixedly connected with described mandrel, in the time of needs welding drum bottom, can directly control hydraulic motor drives roller to rotate, thereby drive to be arranged at bottom that rotary drum on roller makes not weld and to rotate to correct position and weld, without artificial rotating cylinder, welder need not weld in the overhead position, Welding Safety is convenient, and operating efficiency is high.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Embodiment mono-
Portal crane supporting cylinder weld jig shown in Fig. 1, Fig. 2, include roller 8, base plate 5 and be arranged at 2 bracing frames 1 on base plate 5, bracing frame 1 includes support baseboard 1-2 and relative 2 gripper shoe 1-1 that are vertically on support baseboard 1-2, and base plate 5 is bolted to connection with support baseboard 1-2; Roller 8 is all installed between gripper shoe 1-1 by its mandrel 2, two outsides of roller 8 are all set with sheath 4, on base plate 5, offer respectively along its length 4 chutes 6 that slide for bracing frame 1, under support baseboard 1-2, be fixedly connected with the slide block sliding in chute 6; The outside of one of them gripper shoe 1-1 is fixed with the hydraulic motor 7 that 1 driving rolls rotates, and mandrel 2 one end are set with sheath 3, and the other end of mandrel 2 is connected by shaft joint with the output shaft of hydraulic motor 7; The hydraulic fluid port of hydraulic motor 7 is connected with the hydraulic fluid port of pumping plant.
When work, two identical cylinders 9 are placed in frock of the present invention, the face docking that these two cylinders 9 are welded, then welds, and weld seam is 10.
