Description
Technical field
This utility model relates to a kind of fork installation, specifically a kind of engineering machinery pallet fork bracket assembly.
Background technology
User, during with fork installation shovel dress stone, stirs stone through conventional pallet fork, needs putting down stone when
Move backward, pallet fork released below from stone, in the process of moving, owing to the pallet fork that jolts can produce swing, above several often
The operating mode seen all can occur the motion that pallet fork rotates around bracket bearing pin, i.e. rocks, and rocks each cycle of operation of supporter.
The position limiting structure of existing pallet fork, as shown in Figure 14 to Figure 16, welds a L-type hook plate 9, L-type hook plate 9 at pallet fork 2 back
Catch on and be welded at the step of bracket upper backup pad 10, prevent pallet fork 2 with the second bearing pin as axis rotation, i.e. pallet fork 2 is formed
Spacing.Owing to the operation material of engineering machinery fork installation is ratchel, the weight of every block of stone reaches more than 10 ton, the most greatly, because of
In the course of the work, the position limiting structure at pallet fork back is the most cracking, and concrete shortcoming is as follows for the pallet fork of this domestic fork installation:
1. having gap between L-type hook plate 9 and the bracket support plate 10 at pallet fork 2 back, pallet fork is in walking and operation process
Rock, when complete machine oscillation is bigger, it is possible to make thing block drop, cause danger.
2. easily ftracture in the a-quadrant of pallet fork back L-type hook plate 9.Owing to operating mode is more complicated, after pallet fork 2 inserts,
Motionless stone is stuck up in discovery, is sick for reclaiming fork, and during reverse travel, easily ftracture in the a-quadrant of rear side.
3., when jolting occurs in complete machine, owing to thing block is heavier, therefore can rock along with pallet fork 2 one pieces, the a-quadrant of L-type hook plate
Easily cracking, causes driver the most all to worry to be likely to occur potential security incident.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of engineering machinery pallet fork bracket assembly,
Eliminating the gap between existing pallet fork and tray plate, elimination is rocked, and eliminates the defect of existing structure, promotes job security
And reliability.
To achieve these goals, the technical solution adopted in the utility model is: a kind of engineering machinery pallet fork bracket is total
Become, including bracket, pallet fork, be welded on the tray plate of bracket bottom；Described bracket and pallet fork top are connected by the first bearing pin,
Described pallet fork bottom is provided with an installing plate, and installing plate is positioned at above tray plate, by limit between installing plate and tray plate
Position device connects, and limits pallet fork position by stopping means.
This utility model is further, and described stopping means is bolt.
This utility model is further, and described stopping means has multiple.
This utility model is further, and described installing plate is straight template.
This utility model is further, and the through hole on described installing plate is screwed hole, and bolt is by screw thread with installing plate even
Connecing, bolt up or down end face contacts with tray plate.
This utility model is further, and described tray plate is provided with screwed hole, and bolt is by screw thread with tray plate even
Connecing, bolt up or down end face contacts with installing plate.
This utility model is further, described tray plate and installing plate has coaxial screwed hole, is entered by bolt
Row connects and pretension.
This utility model is further, described installing plate has through hole, tray plate are provided with screwed hole, and bolt penetrates logical
Installing plate and tray plate are connected by hole and screwed hole, and carry out pretension.
This utility model is further, and described tray plate is provided with through hole, and installing plate is provided with screwed hole, and bolt passes through
Through hole and screwed hole are connected with tray plate and installing plate, and carry out pretension.
This utility model is further, and described tray plate and installing plate are provided with coaxial through hole, by bolt and spiral shell
Mother is attached and pretension.
Due to foozle, the gap between pallet fork back and bracket is inevitable, therefore use the structure of L-type hook plate without
Opinion design is how perfect, is manufacturing and gap in installation process is inevitable, therefore pallet fork rotate around the second bearing pin or
Rock all inevitable, therefore after pallet fork is assembled on bracket during transport, it is necessary to eliminating gap between the two, this practicality is new
Type uses helicitic texture to eliminate gap, utilizes bolt to be arranged on the screwed hole of pallet fork back installing plate, pre-by bolt
Tightly eliminate gap, so that pallet fork is fixed on bracket, it is impossible to rotate around the first bearing pin, also cannot rock.
Compared with prior art, this utility model employing its advantage of technique scheme is:

Gap is made to eliminate.
2, each pallet fork can use multiple bolt to carry out pretension, to eliminate out-of-balance force and moment of torsion, and therefore pallet fork and bracket
Assembly job stability is more preferable.
3, because of road conditions out-of-flatness cause complete machine oscillation bigger time, this assembly can absorb part by the pretension of screw bolt and nut
Energy.
4, functional reliability is preferable, owing to eliminating the gap at sliding york back and bracket, thus without the old pallet fork back of the body occur
The situation of portion's cracking, reliability is higher.
5, using bolt to carry out pretension, pallet fork eliminates the structure of cracking, and therefore, in work process, safety is higher.
6, maintenance cost of the present utility model is low, and due to long-time heavy duty work, bolt, it is possible that loosen, therefore needs
Make regular check on, and pretension bolt in time, maintenance cost is low.
7, total is simple, and cost is relatively low, compared with old pallet fork, and only many prices of bolt, buy the cost of part
Relatively low with use cost all ratios.
8, work efficiency is higher, owing to eliminating cracking structure, eliminates gap, and working downtime shortens, and efficiency carries
High.
9. the installation pretension of pallet fork back bolt and dismounting are more convenient.
