Description

Technical Field

[0001] The present application relates to the technical field of excavators, and in particular to a safety protection structure for excavator drivers. Background Art

[0002] An excavator is a multifunctional machine that is widely used in mechanical construction such as water conservancy projects, transportation, and earthwork projects. It can effectively reduce heavy physical labor and ensure construction quality while improving production efficiency. At present, the excavator driver operates the excavator's operating lever to operate the digging arm and digging scoop to dig the earth. He cannot pay attention to the sides and back, but can only pay attention to the front. If gravel splashes from the sides and back close to the driver, it is difficult for the driver to discover and avoid it in time, and the driver's personal safety is easily damaged, which in turn causes a safety accident. Utility Model Content

[0003] In order to solve the above-mentioned problem that the excavator driver operates the excavator's operating lever to operate the digging arm and the digging scoop to perform digging operations, but cannot pay attention to the sides and the back. If gravel splashes from the sides and the back and approaches the driver, it is difficult for the driver to discover and avoid it in time, and the driver's personal safety is easily damaged, thereby causing a safety accident. The present application provides a safety protection structure for excavator drivers.

[0004] The present application provides an excavator driver safety protection structure that adopts the following technical solutions:

[0005] The cam is connected with the support frame to form a circle, and the circle is connected with the support frame to form a circle.

[0006] Preferably, the mounting assembly consists of a mounting plate and hexagon socket bolts, the mounting plate is welded to one side of the support plate, there are two hexagon socket bolts, and the two hexagon socket bolts are respectively threaded through both ends of the top of the mounting plate.

[0007] Preferably, the driving assembly consists of a motor and a threaded rod, the motor is fixedly mounted at one end of a fixed frame, the power shaft of the motor rotates and passes through the fixed frame, one end of the threaded rod is welded to the end of the power shaft of the motor, the other end of the threaded rod rotates and passes through one of the inner walls of the fixed frame, and the threaded rod threads pass through the movable block.

[0008] Preferably, a limiting block is welded to one end of the top of the fixing frame, a sliding rod is welded to one end of the top of the supporting frame, and one end of the sliding rod movably passes through the limiting block.

[0009] In summary, the present application includes the following beneficial technical effects: the movable block is pushed to slide inside the fixed frame by the driving assembly, so that the movable block drives the movable rod and the support frame to move, and the support frame drives the fine-mesh wire mesh to move to the outside, thereby blocking the sides and back of the driver. In this way, when the driver operates the excavator's operating lever to operate the digging arm and the digging scoop to dig soil and cannot pay attention to his sides and back, the fine-mesh wire mesh can block the gravel splashed on his sides and back.

[0014] The following is combined with Figure 1-3 This application is described in further detail.

[0015] The present application embodiment discloses a safety protection structure for an excavator driver, referring to Figure 1-3, including two support plates 11, two limit frames 12, a movable rod 21 and a fixed frame 3, the bottom ends of the two support plates 11 are provided with mounting components 5, the mounting components 5 are composed of a mounting plate 51 and a hexagon socket bolt 52, the mounting plate 51 is welded to one side of the support plate 11, there are two hexagon socket bolts 52, the two hexagon socket bolts 52 are respectively threaded through the two ends of the top of the mounting plate 51, and the two hexagon socket bolts 52 are threadedly connected to the top surface of the excavator cab at the same time, then the mounting plate 51 can be fixedly installed on the top surface of the excavator cab, so that the two support plates 11 and the two limit frames 12 are installed on the top surface of the excavator cab, and the two ends of the two limit frames 12 are respectively two support The two ends of the support plate 11 are welded, and the movable rod 21 movably passes through the two limit frames 12. The top end surface of the movable rod 21 is fitted with the inner top wall of the two limit frames 12, and the bottom end surface of the movable rod 21 is fitted with the inner bottom wall of the two limit frames 12. A limiting rod 13 is welded to the inner side wall of one of the two limit frames 12. The two limiting rods 13 pass through the movable rod 21, and the other ends of the two limiting rods 13 are respectively welded to the other inner side wall of the two limit frames 12. The two limiting rods 13 cooperate to guide and limit the movable rod 21, so that the movable rod 21 can only slide in the direction of the two support plates 11. The two ends of the bottom of the fixed frame 3 are respectively welded to the opposite side of the two support plates 11. The support plates 11 can also cooperate to support and fix the fixed frame 3. A support frame 22 is movably provided at the bottom of the fixed frame 3. Two corners of the top of the support frame 22 are respectively welded to the two ends of the bottom of the movable rod 21. The movable rod 21 can support the support frame 22. A fine-mesh wire mesh 23 is welded to the outside of the support frame 22. A movable block 24 is welded to the middle of the top of the movable rod 21. The movable block 24 is slidably connected to the inside of the fixed frame 3. The top surface of the movable block 24 is fitted with the inner top wall of the fixed frame 3. A driving component 4 for driving the movable block 24 to rotate is provided at one end of the fixed frame 3. The driving component 4 is composed of a motor 41 and a threaded rod 42. The motor 41 is fixedly mounted on At one end of the fixed frame 3, the power shaft of the motor 41 rotates and penetrates the fixed frame 3, one end of the threaded rod 42 is welded to the end of the power shaft of the motor 41, and the other end of the threaded rod 42 rotates and penetrates one of the inner walls of the fixed frame 3, and the threaded rod 42 threads through the movable block 24. When the power shaft of the motor 41 drives the threaded rod 42 to rotate, the threaded rod 42 pushes the movable block 24 to slide inside the fixed frame 3 during the rotation process, so that the movable block 24 drives the movable rod 21 and the support frame 22 to move, and the support frame 22 drives the fine-mesh wire mesh 23 to move to the outside, thereby blocking the three sides of the excavator cab, and indirectly blocking the sides and back of the driver.

[0016] Reference Figure 1 , Figure 2 and Figure 3A limiting block 61 is welded to one end of the top of the fixed frame 3, and a sliding rod 62 is welded to one end of the top of the supporting frame 22. One end of the sliding rod 62 movably passes through the limiting block 61, and the top end surface of the sliding rod 62 is in contact with the inner top wall of the limiting block 61. When the sliding rod 62 passes through the limiting block 61, the sliding rod 62 can pull and support one end of the supporting frame 22, so that the supporting frame 22 can maintain a horizontal state continuously.

[0017] The implementation principle of the safety protection structure for an excavator driver in an embodiment of the present application is as follows: before use, after the driver enters the excavator cab and closes the door, the motor 41 is started at this time. When the power shaft of the motor 41 drives the threaded rod 42 to rotate, the threaded rod 42 pushes the movable block 24 to slide inside the fixed frame 3 during the rotation, so that the movable block 24 drives the movable rod 21 and the support frame 22 to move, and the support frame 22 drives the fine-mesh wire mesh 23 to move to the outside, thereby blocking the three sides of the excavator cab and indirectly blocking the sides and one side behind the driver. In this way, when the driver operates the excavator's operating lever to operate the digging arm and the digging scoop to perform digging operations and cannot pay attention to his sides and back, the fine-mesh wire mesh 23 can block the gravel splashed on his sides and back.
