Problems solved by technology

[0003] Existing excavators are digging hard-to-dig pipes or big trees with deep roots, etc., or when the excavator is on a high slope, the excavator is easy to overturn, causing safety problems for the driver, and the glass windows on the cab, etc. The structure is relatively fragile, and it is easy to be broken and damaged when it is subjected to severe vibration or impact by foreign objects, and even splashes out debris, resulting in injury to the driver. Feeling, extra pressure on the body, lack of glass protective structure in the existing device, the glass in the device is easily broken and splashed by external collisions, resulting in danger, once a fire occurs in the device while driving, due to the high position of the cab , it is difficult to evacuate quickly, and it is easy to cause danger

Embodiment 1

[0032] Such as figure 1 As shown, the safety cab of an excavator with a good protective effect in the present invention includes a cab shell 1, and a reinforcing mechanism 2 is provided inside the cab shell 1 to increase the stability of the device structure and prevent the device from being deformed by pressure and falling apart. The reinforcing mechanism 2 The bottom is provided with a shock absorbing mechanism 3, which reduces the vibration of the cab, prevents the cab from being vibrated for a long time, causes the structure to become loose, and affects the health of the driver. The top of the cab shell 1 is provided with a top ventilation mechanism 4. By using the ventilation structure, It is convenient for the air inside the cab to communicate with the outside air, so that the air inside the device is fresher. The front protective mechanism 5 is provided at one end of the cab shell 1 to facilitate the protection of the front of the device. The end of the cab shell 1 away ...

Embodiment 2

[0038] see Figure 1-3 , further improvements have been made on the basis of Example 1:

[0039] In order to increase the stability of the cab shell 1, the number of horizontal plates 21 is two, and the two horizontal plates 21 are welded at both ends of the bottom of the cab shell 1, and two vertical plates 22 are symmetrically welded between the two horizontal plates 21. The two vertical plates 22 can fix the two horizontal plates 21 together to facilitate the fixing of the horizontal plate 21, so that the bottom structure of the cab shell 1 is stably fixed on the horizontal plate 21 and the vertical plate 22, and the top of the horizontal plate 21 is evenly fixed and connected There are four reinforced straight bars 23 and two reinforced curved bars 24, connecting rods 25 are welded between the reinforced straight bars 23, and connecting rods 25 are welded between the reinforced curved bars 24,

[0040] In this embodiment, in order to increase the bending resistance of eac...

Embodiment 3

[0043] see figure 1 with Figure 4 , further improvements have been made on the basis of Example 1:

[0044] In order to increase the protective performance of the device, the top ventilation mechanism 4 includes a hydraulic rod 41 and a fresh air blower 45, the hydraulic rod 41 is fixedly connected to the top of the cab shell 1, and the output end of the hydraulic rod 41 is fixedly connected to a cover plate 42, and the cover plate 42 is away from the hydraulic rod One end of 41 is fixedly connected with clamping plate 43, and the top of the cab shell 1 is provided with a draw-in groove compatible with clamping plate 43 at one end away from hydraulic rod 41, which is convenient for clamping clamping plate 43 and increasing the sealing performance of the device. When the cover 42 moves and is moved by the cover 42, the clamp 43 at one end of the cover 42 is moved and inserted into the slot to protect the miscellaneous net 44 on the top of the cab shell 1 and prevent external ...

Abstract

An excavator safety cab with a good protection effect comprises a cab shell, a reinforcing mechanism is arranged in the cab shell, a damping mechanism is arranged at the bottom of the reinforcing mechanism, a top ventilation mechanism is arranged on the top of the cab shell, a front protection mechanism is arranged at one end of the cab shell, and a balance weight mechanism is arranged at the end, away from the front protection mechanism, of the cab shell. The cab has the beneficial effects that the reinforcing straight rod, the reinforcing bent rod and the connecting rod are used for forming a whole, and the cab shell is prevented from being deformed; a fire extinguishing mechanism is arranged at the top of the counterweight mechanism, and a control box is arranged at the top of an inner cavity of the cab shell; by using a damping block, vibration of the device is reduced; by using the cover plate, external foreign matters are prevented from entering, and by using the fresh air fan, the flowing speed of air is increased; overturning of the excavator is reduced through movement of the balancing weight; the water pump is opened to extract water flow for entering, and fire extinguishing of the device is facilitated; a metal protective net is arranged to protect a glass window located at one end of the front portion of the cab.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to an excavator safety cab with good protection effect. Background technique [0002] An excavator is an important mechanical equipment used to shovel and transport materials to transportation equipment or specified sites. It can mainly help excavate materials such as soil, coal and sediment. Common excavator structures include power devices and working devices , slewing mechanism, operating mechanism, transmission mechanism, walking mechanism and cab, etc. The excavator cab is an important place for the driver to control the excavator. [0003] Existing excavators are digging hard-to-dig pipes or big trees with deep roots, etc., or when the excavator is on a high slope, the excavator is easy to overturn, causing safety problems for the driver, and the glass windows on the cab, etc. The structure is relatively fragile, and it is easy to be broken and damaged when it is subjected...
