Description

Technical Field

[0001] The utility model relates to the technical field of cylinder bodies, in particular to an upper cylinder body of a breaker hammer of an excavator. Background Art

[0002] The upper cylinder is responsible for transmitting the force of the excavator to the working parts of the breaker hammer, so that the breaker hammer can effectively clean floating stones and mud in rock crevices.

[0003] When using the upper cylinder, the upper cylinder is connected to other cylinders and then installed on the excavator for use. When repairing the upper cylinder, the upper cylinder is tightly connected to other cylinders. When separating, a prying tool is inserted into the connection between the upper cylinder and other cylinders to pry and separate the multiple cylinders. However, when using a prying tool, it is easy to damage the upper cylinder, which leads to problems that affect the use of the upper cylinder. Utility Model Content

[0004] The utility model proposes an upper cylinder body for an excavator breaker hammer to solve the problem that when the upper cylinder body is repaired, the upper cylinder body is closely connected with other cylinder bodies. When separating, a prying tool is inserted into the connection between the upper cylinder body and other cylinder bodies to pry and separate the multiple cylinder bodies. However, when the prying tool is used, the upper cylinder body is easily damaged, thereby affecting the use effect of the upper cylinder body.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an upper cylinder body of an excavator breaker hammer, including an upper cylinder body body, a separation device is provided on one side of the upper cylinder body body, and the separation device includes placement grooves opened on both sides of the upper cylinder body body, and the placement grooves on both sides of the upper cylinder body body are located at the connection between the upper cylinder body body and other cylinder bodies, and the placement grooves on both sides of the upper cylinder body body are fixedly connected with fixed blocks, and the internal threads of the fixed blocks are connected with threaded rods, one side of the threaded rod is fixedly connected with an operating block, and one side of the threaded rod is rotatably connected with a separation block.

[0006] The effect achieved by the above components is: when the upper cylinder body is used, the upper cylinder body will be connected with other cylinder bodies and then installed on the excavator for use. When the upper cylinder body is separated from other cylinder bodies for maintenance, the operating block can be rotated to rotate the threaded rod at the fixed block inside the upper cylinder body placement slot, and then the threaded rod drives the separation block to approach other cylinder bodies for squeezing, thereby driving the upper cylinder body to move, and then the upper cylinder body is quickly separated from the other cylinder bodies. By using the separation device, the upper cylinder body can be quickly separated from the other cylinder bodies, and the upper cylinder body can be prevented from being damaged when using a prying tool, thereby improving the use effect of the upper cylinder body.

[0007] Preferably, one side of the separation block is fixedly connected to a limiting rod, and the limiting rod is slidably connected to the fixed block.

[0008] The effect achieved by the above components is: by using the limit rod, the moving track of the separation block is restricted, so that the separation block can move more stably.

[0009] Preferably, a round tube is fixedly connected to one side of the fixing block, and the size of the round tube is matched with the size of the threaded rod.

[0010] The effect achieved by the above components is: by using the round tube, the angle between the threaded rod and the fixed block is limited, thereby preventing the threaded rod and the fixed block from tilting, which would affect the rotation of the threaded rod.

[0011] Preferably, a bearing is fixedly connected to one side of the threaded rod, and an outer ring of the bearing is fixedly connected to the separation block.

[0012] The effect achieved by the above components is: by using the bearing, the friction between the threaded rod and the separation block is reduced, making it easier for the threaded rod to rotate.

[0013] Preferably, protective devices are provided on both sides of the upper cylinder body, and the protective devices include slide grooves opened on both sides of the upper cylinder body, and protective blocks are slidably connected inside the slide grooves on both sides of the upper cylinder body.

[0014] The effect achieved by the above-mentioned components is: when the separation device is not in use, the protective block can be moved so that the protective block moves inside the slide groove on the surface of the upper cylinder body to shield and protect the components of the separation device. By using the protective device, the components of the separation device can be protected, thereby increasing the service life of the separation device.

[0015] Preferably, the size of the protection block is matched with the size of the placement groove, and both sides of the protection block are made of rubber material.

[0016] The effect achieved by the above components is: the friction between the protective block and the slide groove on the surface of the upper cylinder body is improved through the rubber on both sides of the protective block, so that after the protective block moves, it is not easy to slide under the influence of gravity.

[0017] Preferably, a through hole is opened on one side of the protection block, a reinforcing rod is fixedly connected inside the sliding groove on the surface of the upper cylinder body, and the reinforcing rod is slidably connected to the through hole on the surface of the protection block.

[0018] The effect achieved by the above components is: through the reinforcing rod at the internal through hole of the protective block, the connection strength between the protective block and the slide groove on the surface of the upper cylinder body is improved, thereby avoiding the protective block and the slide groove on the surface of the upper cylinder body from separating.

[0019] Preferably, a plurality of anti-sliding blocks are fixedly connected to one side of the protection block, and the plurality of anti-sliding blocks are equidistantly arranged on one side of the protection block.

[0020] The effect achieved by the above components is: by using the anti-sliding block, the friction between the protection block and the operator is increased, so that the protection block is easier to be moved by the operator.

[0021] In summary, the beneficial effects of the utility model are:

[0022] By using the separation device, the upper cylinder body can be quickly separated from other cylinder bodies, and damage to the upper cylinder body when using a prying tool can be avoided, thereby improving the use effect of the upper cylinder body. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Reference Figure 1-4 As shown, this embodiment discloses an upper cylinder of an excavator breaker hammer, including an upper cylinder body 1 , and a separation device 2 is provided on one side of the upper cylinder body 1 .

[0029] Reference Figure 1-4As shown, the present embodiment discloses a separation device 2 including placement grooves 21 provided on both sides of the upper cylinder body 1, the placement grooves 21 on both sides of the upper cylinder body 1 are located at the connection between the upper cylinder body 1 and other cylinder bodies, the placement grooves 21 on both sides of the upper cylinder body 1 are internally fixedly connected with fixing blocks 22, the internal threads of the fixing blocks 22 are internally threadedly connected with threaded rods 23, one side of the threaded rod 23 is fixedly connected with an operating block 24, and one side of the threaded rod 23 is rotatably connected with a separation block 25. When the upper cylinder body is used, the upper cylinder body is connected with other cylinder bodies and then installed on the excavator for use. When the upper cylinder body 1 is separated from the other cylinder bodies for maintenance, the operating block 24 can be rotated to rotate the threaded rod 23 at the fixed block 22 inside the slot 21 of the upper cylinder body 1, and then the threaded rod 23 drives the separation block 25 to approach the other cylinder bodies for squeezing, thereby driving the upper cylinder body 1 to move, and then the upper cylinder body 1 is quickly separated from the other cylinder bodies. By using the separation device 2, the upper cylinder body 1 can be quickly separated from the other cylinder bodies, and damage to the upper cylinder body 1 when using a pry tool can be avoided, thereby improving the use effect of the upper cylinder body 1.

[0030] Reference Figure 1-4 As shown, the present embodiment discloses that one side of the separation block 25 is fixedly connected with a limit rod 26, and the limit rod 26 is slidably connected to the fixed block 22. By using the limit rod 26, the moving trajectory of the separation block 25 is limited, so that the separation block 25 can move more stably. A round tube 27 is fixedly connected to one side of the fixed block 22, and the size of the round tube 27 is adapted to the size of the threaded rod 23. By using the round tube 27, the angle between the threaded rod 23 and the fixed block 22 is limited to avoid the angle between the threaded rod 23 and the fixed block 22 being tilted, which affects the rotation of the threaded rod 23. A bearing 28 is fixedly connected to one side of the threaded rod 23, and the outer ring of the bearing 28 is fixedly connected to the separation block 25. By using the bearing 28, the friction between the threaded rod 23 and the separation block 25 is reduced, so that the threaded rod 23 is easier to rotate.

[0031] Reference Figure 1-4 As shown, the present embodiment discloses that the upper cylinder body 1 is provided with a protective device 3 on both sides thereof, and the protective device 3 includes a slide groove 31 provided on both sides of the upper cylinder body 1, and a protective block 32 is slidably connected inside the slide groove 31 on both sides of the upper cylinder body 1. When the separation device 2 is not in use, the protective block 32 can be moved so that the protective block 32 moves inside the slide groove 31 on the surface of the upper cylinder body 1 to shield and protect the components of the separation device 2. By using the protective device 3, the components of the separation device 2 can be protected, thereby improving the service life of the separation device 2.

[0032] Reference Figure 1-4As shown, this embodiment discloses that the size of the protective block 32 is adapted to the size of the placement groove 21, and the two sides of the protective block 32 are made of rubber. The rubber on both sides of the protective block 32 is used to increase the friction between the protective block 32 and the surface groove 31 of the upper cylinder body 1, so that after the protective block 32 moves, it is not easy to slide under the influence of gravity. A through hole 33 is provided on one side of the protective block 32, and a reinforcing rod 34 is fixedly connected inside the surface groove 31 of the upper cylinder body 1, and the reinforcing rod 34 is slidably connected to the through hole 33 on the surface of the protective block 32. The reinforcing rod 34 at the through hole 33 inside the protective block 32 is used to increase the connection strength between the protective block 32 and the surface groove 31 of the upper cylinder body 1, so as to avoid the protective block 32 and the surface groove 31 of the upper cylinder body 1 from separating. A plurality of anti-sliding blocks 35 are fixedly connected to one side of the protective block 32, and the plurality of anti-sliding blocks 35 are arranged equidistantly on one side of the protective block 32. By using the anti-sliding block 35, the friction between the protection block 32 and the operator is increased, so that the protection block 32 can be moved more easily by the operator.

[0033] Working principle: When using the upper cylinder, the upper cylinder will be connected to other cylinders and then installed on the excavator for use. When the upper cylinder body 1 is separated from other cylinders for maintenance, the operating block 24 can be rotated to rotate the threaded rod 23 at the fixed block 22 inside the upper cylinder body 1 placement slot 21, and then the threaded rod 23 with the bearing 28 drives the separation block 25 close to other cylinders for extrusion. At this time, the limit rod 26 is used to limit the movement trajectory of the separation block 25, thereby driving the upper cylinder body 1 to move, and then the upper cylinder body 1 is quickly separated from the other cylinders. By using the separation device 2, the upper cylinder body 1 can be quickly separated from the other cylinders, and the damage to the upper cylinder body 1 when using the prying tool can be avoided, thereby improving the use effect of the upper cylinder body 1.

[0034] When the separation device 2 is not in use, the protective block 32 with the anti-sliding plate 35 can be moved so that the protective block 32 moves inside the slide groove 31 on the surface of the upper cylinder body 1. At this time, the reinforcing rod 34 at the through hole 33 inside the protective block 32 can be used to increase the connection strength between the protective block 32 and the slide groove 31 on the surface of the upper cylinder body 1, and then the components of the separation device 2 can be shielded and protected. By using the protective device 3, the components of the separation device 2 can be protected, thereby increasing the service life of the separation device 2.
