Description
Technical field
The invention belongs to Tunnel testing technical field, relate to a kind of Tunnel testing telescopic machine mechanical arm.
Background technology
Railway is the main artery of national economy, is the important infrastructure of country.China's railway total kilometrage at present reaches more than 100,000 kilometer, and wherein high-speed railway mileage about 20,000 kilometers occupy more than the 50% of whole world high ferro ratio, occupy the first in the world.Chinese Regional is vast, is again the country on many mountains, has the railway tunnel that the world is most.The railway tunnel of China is widely distributed, complex geologic conditions.Tunnel structure all can be impacted by geological movement, plant growth, and train operation is constituted great potential safety hazard.Find the structural issue that tunnel occurs, and early warning in time the most in time, assure the safety for life and property of the people, be an important mission of all railway servant particularly railway scientific workers.Tunnel situation varies, and varies, and has height to have low, has width to have narrow；The each 50m of tunnel vault is provided with high-tension electricity coil holder, coil holder height 1-1.5m；Vault surface smoothness also has difference, frequently there will be the step of projection, the reinforcing bar emerged during detection.At present, hydraulic lifting equipment is used to drive radar to go upward at keystone, realize testing goal, owing to hydraulic lifting equipment is bulky, speed is slow, cannot meet rising or falling speed requirement, even if using electric lifting rod, prestissimo also only has 200mm/s, then loss reaches 20%, also cannot meet the requirement of detection.
Summary of the invention
The present invention is directed to the problems referred to above, it is provided that a kind of Tunnel testing telescopic machine mechanical arm, this device volume is little, and rising or falling speed is fast, angle adjustable, and action can realize being precisely controlled.
According to technical scheme: a kind of Tunnel testing telescopic machine mechanical arm, it is characterized in that: include pedestal, base-plates surface installs beat base, transmission case is connected by axis of rotation on beat base, fixing connection installing frame on transmission case, installing frame is installed many displacements of cylinders, described many displacements of cylinders lower end is fixing with transmission case to be connected, and at described transmission case sidepiece, gearbox is installed, the input of gearbox installs motor, the output shaft of gearbox stretches in transmission case, tape winder on output shaft of gear-box is fixing with transmission band one end to be connected, the described transmission band other end is fixing with the top of many displacements of cylinders to be connected, rotary head is installed on described more piece cylinder top, radar mounting bracket is installed on described rotary head.
As a further improvement on the present invention, described pedestal being respectively provided with a collateral seat corresponding to two ends before and after beat base, each collateral seat is all connected with a spiral strut, and described spiral strut upper end is connected with the connecting shaft on installing frame.
The method have technical effect that: product structure of the present invention is simple, operationally can realize the fast lifting operation of many displacements of cylinders, so that according to the situation of tunnel vault, regulate the flexible situation of many displacements of cylinders at any time, reach the purpose avoiding telescopic cylinder top to encounter vault, owing to the many displacements of cylinders in product of the present invention are also connected with transmission band simultaneously, during vault is detected, when running into barrier, many displacements of cylinders can quickly carry out contractive action, speed is controlled, barrier encountered by the radar being prevented effectively from radar mounting bracket, simultaneously, installing frame can carry out the swing in the range of certain amplitude, realize a range of detection.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is further described.
In Fig. 1, including pedestal 1, beat base 2, transmission case 3, gearbox 4, motor 5, collateral seat 6, spiral strut 7, installing frame 8, many displacements of cylinders 9, rotary head 10, radar mounting bracket 11, transmission band 12 etc..
As shown in Figure 1, the present invention is a kind of Tunnel testing telescopic machine mechanical arm, including pedestal 1, beat base 2 is installed on pedestal 1 surface, transmission case 3 is connected by axis of rotation on beat base 2, fixing connection installing frame 8 on transmission case 3, installing frame 8 is installed many displacements of cylinders 9, described many displacements of cylinders 9 lower end is fixing with transmission case 3 to be connected, and at described transmission case 3 sidepiece, gearbox 4 is installed, the input of gearbox 4 installs motor 5, the output shaft of gearbox 4 stretches in transmission case 3, tape winder on gearbox 4 output shaft is fixing with transmission band 12 one end to be connected, described transmission band 12 other end is fixing with the top of many displacements of cylinders 9 to be connected, rotary head 10 is installed on described many displacements of cylinders 9 top, radar mounting bracket 11 is installed on described rotary head 10.
Being respectively provided with a collateral seat 6 corresponding to two ends before and after beat base 2 on pedestal 1, each collateral seat 6 is all connected with a spiral strut 7, and described spiral strut 7 upper end is connected with the connecting shaft on installing frame 8.
The course of work of the present invention is as follows: product of the present invention operationally, is installed on dedicated test car, installs radar in radar mounting bracket 11, and dedicated test car is in detection operation process, not parking, and efficiency is high.During detection, the gait of march of dedicated test car is 2Km/h, hides the high coil holder of 1.5m, and the time rising and declining will be less than 4S, is only possible to reach the verification and measurement ratio of more than 90%.Many displacements of cylinders 9 in product of the present invention are when stretching out and when retracting, speed, the most displacements of cylinders 9 are when stretching out, the air cavity of many displacements of cylinders 9 is inflated process, the most displacements of cylinders 9 are stretched out step by step, until radar mounting bracket 11 top extend out to tunnel vault position, the radar in radar mounting bracket 11 carry out detecting operation to vault situation.When running into barrier, many displacements of cylinders 9 carry out deflating action, each displacements of cylinders carries out recovery action, and meanwhile, motor 5 drives transmission band 12 to carry out drum action via gearbox 4, auxiliary movement due to motor 5, many displacements of cylinders 9, under the effect of transmission band 12, are quickly packed up, and the prestissimo packed up is more than 200 mm/s, guarantee that many risings of displacements of cylinders 9 and the time of decline are both less than 4s, it is possible to achieve the verification and measurement ratio of more than 90%.Due to the effect of spiral strut 7, the many displacements of cylinders 9 in product of the present invention can make the swing of certain amplitude towards pedestal 1 length direction both sides, to realize detection a range of to vault.
Product of the present invention is when being installed on dedicated test car, generally use three groups of vault detection equipment constituting complete set, it is achieved for the detection of tunnel vault concrete situation, and three groups of products of the present invention are when arranging, the most seamless cooperation can be realized, it is achieved for effective detection of vault.
