The pedestal is arranged on the experiment platform. The top beam is supported by the support column and is hinged to the shield beam. The front end of the shield beam is hinged to the rear end of the top beam. The rear end of the shield beam forms a four-connecting rod mechanism with the pedestal via the connecting rods. A steel plate is vertically arranged on one side of the experiment table, and the steel plate is provided with the loading devices. The top beam is provided with the force sensor. The sensor is connected with a force analyzing instrument to sense the force on the support, and the force can be controlled artificially via a spiral loading device. According to the structural characteristics of the model, the model can be dismounted and then assembled into various hydraulic support models. The model can be loaded on the experiment table, and a detection device can analyze the performance of the support.
Description
Technical field
The utility model relates to hydraulic support model experiment equipment, particularly hydraulic support is carried out loading experiment, force analysis, and then detects the performance of hydraulic support.The utility model also relates to a kind of hydraulic support model through different hinged combinations, simulates the hydraulic support model of multiple different model.
Background technology
The hydraulic support experiment table is a kind of equipment that the technical feature of hydraulic support and security performance are detected and test.Along with the continuous development of coal in China industry, hydraulic support becomes the major equipment of coal mine support gradually, and its security, stability influence very big to the safety in production of fully-mechanized mining working.In order to guarantee safety, to produce efficiently, it is very important that the Performance Detection of hydraulic support becomes.To the hydraulic support at scene detect be the most truly, the most reliable, but this experiment is not easy to realize at the scene, also can run into a lot of other difficulties, carries out Performance Detection again after on-the-spot and also lost the meaning that detects if apply to support by the time.Produced real hydraulic support is detected needed site environment also be difficult to simulation.Therefore, can design the hydraulic support model, to simulating behind its stressed bi-directional scaling.The now domestic experiments that also have a lot of about the hydraulic support detection, experimental situation is fixed, and also will make different support models, model function singleness, bad adaptability to different support experiments.In sum, just want to design a kind of can be in the laboratory usefulness, and the model that model can different hydraulic test demands.
Summary of the invention
Can only do the deficiency of an experiment in order to overcome the difficult and a kind of support model that hydraulic support is detected at stope, the utility model provides a kind of can simulate hydraulic support model experiment platform multiple type, that the laboratory is used.
The utility model solves the technical scheme that its technical matters adopted: a kind of hydraulic support model experiment platform, comprise experiment table, and be placed on the hydraulic support foundation on the experiment table; Form four-bar mechanism through front-rear linkage between base and the caving shield, back timber is hinged by shore supports and caving shield, is connected on the pillar to test instrument stressed and distortion; In order to detect the stressed and stroke of pillar; Charger is arranged on the vertical riser on the experiment table, and (on the riser that has two translots, upper and lower groove respectively has a cover charger, and every suit charger has two screw rods again; Through exerting pressure to back timber under the screw; Every suit charger on the translot can laterally move in translot, and the back timber diverse location is pressurizeed), the passing ratio convergent-divergent is in order to the load of simulation support top.Four screw rods that load are responsible for the loading in four zones of back timber; Sensor (8) through connect device for measuring force can be used for detecting back timber stressed size; So that the stand under load to back timber is controlled, the lower position coupling arrangement of pillar (5) can be tested the stressed and stroke of pillar.Through the hydraulic support loading experiment, simulation hydraulic support stressing conditions is at the scene observed its situation that may occur, and analyzes the performance of hydraulic support.Back timber, caving shield, base all are to be welded together by the steel plate that punches to constitute; The position of the back timber of model and caving shield, caving shield and base, pillar is all through hinged realization; In twos through different articulated position; The connecting rod assembly of different length makes between each parts of hydraulic support it is not unalterable together, can be through the hydraulic support of a variety of types of different combinations simulation.So just avoided to make the trouble of different model support model to the experiment of different model support.
Advantage and the good effect that the utlity model has are: the position of the back timber of model support and caving shield, caving shield and base, pillar is all through hinged realization; The position can change flexibly; Therefore can simulate multiple hydraulic support, the hydraulic support of different model is experimentized.The charger of model can the simulated field support roof pressure, the device for measuring force on the top board can detect and control support force through sensor, and then can the technical feature and the security performance of hydraulic support be detected and test.Model structure is simple, and compact volume and convenience can be used for the model displaying and also can carry out loading experiment.

Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model; Now the following examples of giving an example; And conjunction with figs. specifies as follows: if do the experiment of a certain type support, elder generation is individual to accomplish the assembling of support model on experiment table according to major parameter.A kind of hydraulic support model experiment platform comprises experiment table 1, and hydraulic support foundation 2, back timber 4 are supported by pillar 5 and be hinged with caving shield 3, and caving shield 3 is connected and support shield beam 3 through front-rear linkage 6 with base 2.They are combined and form a hydraulic support model.Charger 7 is through applying a power on back timber 4 under the screw; Pass to base 2 through pillar 5 and connecting rod 6; Device on the pillar 5 can be measured suffered power of pillar and pillar stroke; Force cell 8 on back timber 4 connects other devices and detects and control loaded device 7 applied forces, and then detects the performance of support.The length of the back timber 4 of support, caving shield 3, connecting rod 6, pillar 5 can change through different hinged realizations with the position, and then simulates dissimilar hydraulic supports.This is the characteristics place of this utility model.We can find out that from the novel structural representation of this experiment charger has four screw rods in addition.If divide four zones to set cap top, these four screw rods just are responsible for the stand under load simulation in these four zones respectively so, help the variation of simulated field true environment better like this.
