Abstract
The utility model discloses a kind of front lower slide block devices of suspension arm of lorry-mounted crane, it is related to lifting equipment field, it include preceding sliding block, limited block and adjustment gasket, the limited block is set as 2, before being fixedly installed on respectively by screw on the surface at sliding block both ends, 2 limited blocks are bolted on respectively on the inner surface of boom, when assembling boom, the lower part of sliding block and both ends limited block entirety before the adjustment gasket is set to.The utility model is easy to assembly, ensure that preceding sliding block and the contact area of limited block in the Z-axis direction, and sliding block firmly installs not easily to fall off in hoisting arm expansion operation process before making.
Description
Technical field
The utility model relates to lifting equipment field, the preceding sliding block of specifically a kind of suspension arm of lorry-mounted crane is filled
It sets.
Background technique
Suspension arm of lorry-mounted crane stretch operation when, sliding block is the important bearing and friction group of relative motion between boom cylinder
Part.It is limited to suspension arm of lorry-mounted crane assembly technology process, preceding sliding block assembly space is narrow.Currently, the common dress of preceding sliding block
It is that limited block, another side bolt assembling activity limited block, by preceding sliding block lower part is welded and fixed in three side of sliding block with form
Increase the method for adjustment gasket, adjusts the fit-up gap between boom and top shoe.The limited block of preceding sliding block surrounding can only be about
Beam front-slider X-axis and Y-axis freedom degree；Preceding sliding block lower part is encased inside adjustment gasket, and sliding block and limited block are in Z-direction before causing
Contact area reduces.Sliding block is easy to fall off in hoisting arm expansion operation process before sliding block installation form makes before this kind.
Summary of the invention
To solve above-mentioned technical problem, the utility model provides a kind of preceding sliding block dress of suspension arm of lorry-mounted crane
It sets, it is easy to assembly, it ensure that preceding sliding block and the contact area of limited block in the Z-axis direction, sliding block is in hoisting arm expansion before making
It is firmly installed in operation process not easily to fall off.
The utility model solve its technical problem the technical solution adopted is that:
A kind of front lower slide block device of suspension arm of lorry-mounted crane includes preceding sliding block, limited block and adjusts gasket, described
Limited block is set as 2, before being fixedly installed on respectively by screw on the surface at sliding block both ends, 2 limited block difference
It is bolted on the inner surface of boom, when assembling boom, sliding block and both ends are limited before the adjustment gasket is set to
The lower part of block entirety.
4 threaded holes are set on the limited block, and corresponding with four through-holes on boom, being realized by bolt will limit
Block is fixed on boom inner surface.
The utility model structure is simple, the both ends of sliding block before limited block is fixedly mounted on by tenon structure, then leads to
Cross the inner surface that the limited block at both ends is fixed on boom by bolt, constrain before sliding block in X-axis, Y-axis, Z-direction from
By spending, the lower part of sliding block before gasket is encased inside will be adjusted when assembling boom, thus limited block is also whole padded, guarantee limited block
Contact area is inconvenient in the Z-axis direction between preceding sliding block, and sliding block falls off in hoisting arm expansion operation process before avoiding, and fills
It is convenient and efficient with by screw and bolt, it firmly installs.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the structural schematic diagram of preceding sliding block；
Fig. 3 is the structural schematic diagram of limited block.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments:
As shown in Figure 1-3, the front lower slide block device of the suspension arm of lorry-mounted crane, sliding block 1,4 and of limited block before including
Gasket 3 is adjusted, the limited block 2 is set as 2, before being fixedly installed on respectively by screw 2 on the surface at 1 both ends of sliding block, 2
Limited block 4 described in part is fixed on the inner surface of boom by bolt 5 respectively, and when assembling boom, the adjustment gasket 3 is set to
Preceding sliding block 1 lower part whole with both ends limited block 2.
4 threaded holes are set on the limited block 2, and corresponding with four through-holes on boom, being realized by bolt will limit
Position block 2 is fixed on boom inner surface.
The installation process of this downslide block assembly is specifically introduced in the present embodiment.Firstly, 2 limited blocks 4 are consolidated by screw 2
Before being scheduled on the surface at 1 both ends of sliding block.Bolt 5 passes through 4 threaded holes on 4 through-holes and limited block 4 on boom, will limit
Position block 4 is mounted on boom inner surface fixed.In this way, the limited block 4 at both ends is mutually constrained by joinery and its construction, realize to preceding
Sliding block 4X axis, Y-axis, the freedom degree on three directions of Z axis, are fixedly secured preceding sliding block 1 in boom inner surface.
When assembling boom, by being encased inside adjustment gasket 3 in preceding 1 lower part of sliding block, the dress between boom and top shoe is adjusted
With gap, since limited block 4 and preceding sliding block 1 are padded simultaneously, limited block 4 and preceding sliding block 1 contact area in the Z-axis direction
It is constant, so as to avoid sliding block falling off during hoisting arm expansion, firmly install, securely and reliably.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in the essential scope of the utility model, are also answered
Belong to the protection scope of the utility model.
