Abstract

The utility model provides a tool for manufacturing a lower support of a tower crane. The tool is firm, reliable and high in adjustment accuracy and comprises a working platform. A jacking frame locating plate is welded in the middle of the working platform. The four corners of the working platform are respectively provided with a tool clamping die. Two installing holes are formed in each tool clamping die. Through holes corresponding to the installing holes are formed in the working platform. Locating spigot sleeves are arranged in the installing holes and the through holes. Locating pins are arranged in the locating spigot sleeves, and pressing blocks are arranged on the tool clamping dies and press the two locating stopping sleeves. By the adoption of the tool for manufacturing the lower support of the tower crane, the tool clamping dies are conveniently demounted, mounted and interchanged, and the tool has the advantages of being simple in structure and high in machining efficiency and saving time and labor.

Description

The undersetting of derrick crane is made frock
Technical field
The utility model relates to a kind of making frock of crane, and especially a kind of undersetting of derrick crane is made frock.
Background technology
The undersetting of derrick crane is the middle transition device that derrick crane connects, its bottom and standard knot jacking stock connect and belong to the fixed rigid body structure, top connects with slewing tower by pivoting support, top belongs to rotary body, extra than the curved weak point of large eccentricity for guaranteeing not produce, so the up and down plane parallelism of undersetting, intermediate vertical degree and the required precision of attachment pegs axis hole are all higher.
The undersetting of making in the past all needed with the jacking stock mutually equipped, and stupid, large, thick because of workpiece, not only time-consuming but also effort, and the undersetting of making can not be replaced mutually, brings inconvenience for production, installation, the use of hoisting machinery.
The utility model content
The purpose of this utility model provides a kind of undersetting solid and reliable, that adjust the high derrick crane of precision and makes frock.
Realize the undersetting making frock of the derrick crane of the utility model purpose, comprise workbench, the centre of described workbench is welded with the jacking frame location-plate, and four angles of described workbench are respectively equipped with a frock snap gauge; Be respectively equipped with two installing holes on the described frock snap gauge, described tooling platform is provided with the through hole corresponding with described installing hole, be provided with the positioning spigot cover in described installing hole and the through hole, be provided with alignment pin in the described positioning spigot cover, described frock snap gauge is provided with briquetting, and described briquetting is pressed in two positioning spigot cover tops.
Being shaped as of described positioning spigot cover is outside cylindrical, and it is conical that inside is.
Described frock snap gauge is provided with locating dowel, and described locating dowel is provided with locating hole, and described locating dowel both sides respectively are provided with an adjusting screw.
The beneficial effects of the utility model are as follows: the undersetting of derrick crane of the present utility model is made frock, and it is convenient to remove and install the frock snap gauge, is convenient to exchange the frock snap gauge, simple in structure, time saving and energy saving, has improved working (machining) efficiency.
Description of drawings
Fig. 1 is that the undersetting of derrick crane of the present utility model is made the structural representation of frock.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
The specific embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, 2, 3, the undersetting of derrick crane of the present utility model is made frock, comprise workbench 1, the centre of described workbench 1 is welded with jacking frame location-plate 7, and four angles of described workbench 1 are respectively equipped with a frock snap gauge 8; Be respectively equipped with two installing holes on the described frock snap gauge 8, described tooling platform 1 is provided with the through hole corresponding with described installing hole, be provided with positioning spigot cover 6 in described installing hole and the through hole, be provided with alignment pin 5 in the described positioning spigot cover 6, described frock snap gauge 8 is provided with briquetting 4, and described briquetting 4 is pressed in two positioning spigots and overlaps 6 tops.
Being shaped as of described positioning spigot cover 6 is outside cylindrical, and it is conical that inside is.
Described frock snap gauge 8 is provided with locating dowel 9, and described locating dowel 9 is provided with locating hole 2, and described locating dowel 9 both sides respectively are provided with an adjusting screw 3.
The beneficial effects of the utility model are as follows: lower plane is regulated the horizontal base on plane on the workbench 1 by the clearance gauge pad through fine finishining on the workbench 1, and the bottom is by foundation bolt and basic positive connection; Plane welding jacking frame connection location-plate 7 on workbench 1 is regulated screw mandrel 3 and is regulated gap between welded plate and the jacking frame location-plate 7 by screwing out and tightening, and leans on locating hole 2 to determine the relative position of welded plate.
Press 8 through holes of figure paper conversion at workbench 1, be pressed into positioning spigot cover 6, positioning spigot cover 6 is used to settle the standard with alignment pin 5 and saves the relative position of coupling sleeve, by briquetting 4, and the relative position of the joint main chord that settles the standard.Briquetting 4 is detachable, its Main Function: 1. decide the main chord of standard section relative position, 2. block the relative position of positioning spigot cover 6,3. remove briquetting 4 and positioning spigot can be overlapped 6 taking-ups, be convenient to exchange the frock snap gauge; Positioning spigot overlaps pressured 4 location, 6 tops, and use when guaranteeing to dismantle mould by 1 time block location of workbench the bottom.
Embodiment recited above is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
