In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
an excavator counterweight support assembly, comprising: one side of the beam extends outwards to form two supporting beams, and through holes are vertically formed in the upper edges of the supporting beams;
the bearing frame is sleeved on the supporting beam in a sliding structure mode, and mounting grooves matched with the through holes are formed in the bottom surface and the top surface of the bearing frame;
the connecting beam is arranged between the two bearing frames in a fixed structure mode;
and one end of the screw rod is connected with the cross beam in a rotating structure mode, and the other end of the screw rod is connected with the connecting beam in a threaded structure mode.
Furthermore, a hand wheel is arranged at one end, far away from the connecting beam, of the screw rod through the cross beam.
Furthermore, one end, far away from the crossbeam, of the screw rod is provided with a limiting plate, and the connecting beam can move between the limiting plate and the crossbeam.
Furthermore, the connecting beam is arranged on one side, close to the cross beam, of the bearing frame, and the vertical surface of the left side of the connecting beam is flush with the inside of the left side of the bearing frame.
Furthermore, the bearing frame is of a rectangular structure, and a chamfer angle structure is arranged at the outer side corner of the upper part.
The utility model has the advantages that: by arranging the bearing frame, the balancing weight can be directly clamped on the upper part of the bearing frame, the position of the balancing weight on the supporting beam is adjusted by utilizing the sliding property of the bearing frame, and the position of the balancing weight does not need to be adjusted by multiple persons under a hoisting state, so that the occurrence of danger is reduced, and the installation efficiency is improved; utilize the screw rod to pass through even roof beam drive carriage to suitable position, saved workman's physical power, simple structure realizes more easily, and occupation space is less, has optimized the design.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of an embodiment of the present invention.
In the figure:
1. crossbeam, 2, thrust beam, 3, through-hole, 4, bearer frame, 5, mounting groove, 6, even roof beam, 7, screw rod, 8, hand wheel, 9, limiting plate.
The specific implementation mode is as follows:
in order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings and the following examples so that the public can better master the method of implementing the present invention, and the specific embodiments of the present invention are:
an excavator counterweight support assembly, comprising: crossbeam 1 of excavator body frame, crossbeam 1 one side outwards extends has two thrust beam 2, and the vertical through-hole 3 that is provided with is followed on the thrust beam 2, and the through-hole can utilize the bolt to fix the counter weight on the thrust beam 2.
The bearing frame 4 is sleeved on the supporting beam 2 in a sliding structure mode, so that the position of a balance weight does not need to be adjusted by multiple people under a lifting state, the occurrence of danger is reduced, and the installation efficiency is improved; bearing frame 4 bottom surface and top surface are seted up with through-hole 3 complex mounting groove 5, and mounting groove 5 possesses certain length, no matter where bearing frame 4 is placed to the counter weight, can both guarantee that the bolt passes mounting groove 5 and connects the counter weight.
The connecting beam 6 is arranged between the two bearing frames 4 in a fixed structure mode; screw rod 7, screw rod 7 one end links to each other with crossbeam 1 with the rotating-structure mode, and the other end links to each other through the helicitic texture mode with linking roof beam 6, utilizes screw rod 7 and links roof beam 6's cooperation, drives two bearing frame 4 motions, saves operating personnel physical demands.
One end of the screw 7, which is far away from the connecting beam 6, penetrates through the cross beam 1 to be provided with a hand wheel 8, so that the operation of workers is facilitated.
The one end that crossbeam 1 was kept away from to screw rod 7 is provided with limiting plate 9, links roof beam 6 and can move about between limiting plate 9 and crossbeam 1, guarantees screw rod 7 and links roof beam 6 screw-thread fit relation.
The connecting beam 6 is arranged on one side, close to the cross beam 1, of the bearing frame 4, and the vertical surface of the left side of the connecting beam 6 is flush with the inside of the left side of the bearing frame 4, so that the distance between the connecting beam 6 and the cross beam 1 is reduced as much as possible, and the occupation of a counterweight space is reduced.
