Abstract
The invention discloses a combined symmetrical clump weight for truck-mounted cranes, which comprises a combined middle clump weight, at least one left clump weight and at least one right clump weight, wherein the combined middle clump weight is composed of a bottom clump weight and an upper clump weight, the upper end face of the bottom clump weight is provided with a lug boss, the lower end face of the upper clump weight is provided with a groove matched with the lug boss, the two opposite sides of the upper clump weight are provided with mortises and the other two sides of the upper clump weight are provided with lifting lugs, a mortise and a lifting lug are arranged at the positions, corresponding to the upper clump weight, of the bottom clump weight, the left clump weight and the right clump weight are respectively provided with a hanging lug, and the left clump weight and the right clump weight are respectively butt-jointed and spliced together with the mortise on the bottom clump weight by the lifting lugs. Because an integrally formed clump weight is heavy and is large in volume, great inconvenience is frequently brought to the transportation and installation of the clump weights. According to the weight, through removable arrangement, the demands of truck-mounted cranes with different tonnages can be satisfied by increasing or decreasing the number of the clump weights; and the clump weights are symmetrically arranged, so that the installation and the balancing of the clump weights are convenient, and also the required cost for assembling clump weights in different sizes and shapes can be reduced.
Description
Technical field
The present invention relates to clump weight, refer to that a kind of compound type symmetric car hangs clump weight particularly.
Background technology
In order to reduce the weight of wheel crane self, large automobile crane will remove counterweight when walking, if install counterweight again during construction, conveniently installs counterweight, so in general large automobile crane all adopts the method installation vehicle body counterweight from installing.Counterweight is generally the block one-piece construction that cast iron materials is formed, although structure is simple, because weight is large, bulky, usually gives transport and installs and cause very large inconvenience.In addition, for the different tonnage demand of wheel crane, need the clump weight configuring different size and shape, which adds the cost of counter weight device.
Summary of the invention
The object of the invention is to the weak point overcoming above-mentioned existing background technology, and provide a kind of compound type symmetric car to hang clump weight, the demand of satisfied different tonnage wheel crane can be carried out by the magnitude setting increasing or reduce loss of weight block.
The object of the invention is to reach by following technical solution: compound type symmetric car hangs clump weight, the combination middle weight block be made up of end clump weight and upper clump weight, its special character is, it also comprises at least one left clump weight and at least one right clump weight, clump weight upper surface, the described end is provided with boss, described upper clump weight lower surface is provided with the groove coordinated with boss, the both sides that described upper clump weight is relative are provided with tongue-and-groove, both sides are provided with hanger in addition, clump weight of the described end position corresponding with upper clump weight is also provided with tongue-and-groove and hanger, described left clump weight and right clump weight are respectively equipped with hangers, described left clump weight and right clump weight dock chimeric respectively by hangers with the tongue-and-groove on end clump weight.
Preferably, multiple middle weight block is provided with between clump weight of the described end and upper clump weight, described middle weight block upper surface is provided with boss, the described middle weight block lower surface that is provided with is provided with groove, and described middle weight block realizes removably connecting by the boss that matches and groove with end clump weight and upper clump weight respectively.
Further, described left clump weight is 1 ~ 3.
Further, described right clump weight is 1 ~ 3.
Further, between described left clump weight and combination middle weight block, there is left clump weight, between described right clump weight and combination middle weight block, have right clump weight.
The present invention is by arranging clump weight at the bottom of detouchable, upper clump weight, left clump weight and right clump weight, the demand of satisfied different tonnage wheel crane can be carried out by the magnitude setting increasing or reduce clump weight, and be arranged symmetrically, convenient installation and balance, decrease the cost needed for the clump weight owing to configuring different size and shape simultaneously.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in figures 1-4, the present invention includes the combination middle weight block 12 be made up of end clump weight 1 and upper clump weight 2, it also comprises at least one left clump weight 3 and at least one right clump weight 4, clump weight 1 upper surface, the described end is provided with boss, described upper clump weight 2 lower surface is provided with the groove 8 coordinated with boss, the both sides that described upper clump weight 2 is relative are provided with tongue-and-groove 5, both sides are provided with hanger 6 in addition, clump weight of the described end 1 position corresponding with upper clump weight 2 is also provided with tongue-and-groove and hanger, described left clump weight 3 and right clump weight 4 are respectively equipped with hangers 9, described left clump weight 3 and right clump weight 4 dock chimeric respectively by hangers 9 with the tongue-and-groove 5 on end clump weight 1.
In addition, multiple middle weight block 7 is provided with between clump weight of the described end 1 and upper clump weight 2, described middle weight block 7 upper surface is provided with boss, described middle weight block 7 lower surface that is provided with is provided with groove, and described middle weight block 7 realizes removably connecting by the boss that matches and groove with end clump weight 1 and upper clump weight 2 respectively.
In addition, described left clump weight 3 is 1 ~ 3, and described right clump weight 4 is 1 ~ 3.
In addition, between described left clump weight 3 and combination middle weight block 12, there is left clump weight 10, between described right clump weight 4 and combination middle weight block 12, have right clump weight 11.
During use, can correspondingly increase or reduce the magnitude setting of clump weight as required.
Other unspecified part is prior art.
