The equipment needing to be pushed (pulled) is installed and fixed on the clamp holder, the connecting wire is fixed on the clamp holder and is controlled in the guide groove of the guide rail through the screw and the nut indicating smoothness, the connecting wire is connected with the counterweight steel column through the pulley which is glued at the end of the guide rail through the metal glue, and the downward gravity of the counterweight steel column with certain mass is converted into constant pushing and pulling force in the horizontal direction.
Description
Technical Field
The utility model relates to a can provide simple and easy device of invariable push-and-pull power, be applicable to the test system that needs controlgear to carry out unidirectional motion under invariable push-and-pull power.
Background
For some equipment needing unidirectional motion, an equipment moving device capable of providing constant pushing and pulling force can control experimental variables, and the use error of the equipment is reduced. The existing mobile operation type equipment mostly adopts manual control to push and pull force to realize equipment displacement, the power magnitude is difficult to accurately control, the influence of subjective factors is caused, the instability of applied force is high, and in addition, part of devices are controlled by adopting an electromagnetic means, so that the equipment is precise, the manufacturing cost is high, the operation is complex, and faults are easy to occur. In order to better simulate the operation condition of equipment under constant push-pull force, an equipment motion control device which has a simple and stable structure and can keep constant push-pull force is needed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a can provide the simple and easy device of invariable push-and-pull power to current permanent power equipment motion control device existence, the utility model designs a invariable push-and-pull power is applyed through fixed pulley and connecting wire to the adoption counter weight steel column, and the device is simple and easy, can provide invariable push-and-pull power for controlgear unidirectional movement.
The utility model discloses constitute by 7 parts such as support (1), equipment holder (2), guide rail (3), pulley (4), scale (5), counter weight steel column (6), connecting wire (7). The equipment that will push away (draw) to move is installed and is fixed on holder (2), it is fixed in the gap that connecting wire (7) inserted equipment holder and equipment, there is the screw equipment holder (2) bottom, control in the guiding groove of guide rail (3) through the screw rod with show smooth nut, it makes equipment keep uniform motion to pull connecting wire (7) with the tensiometer, measure the frictional force that this equipment corresponds, the connecting wire connects counter weight steel column (7) through metal-to-metal adhesive joint pulley (4) at guide rail (3) end, scale (5) directly paste in the guide rail both sides, guide rail (3) are through metal-to-metal adhesive joint on support (1), according to scale (5) numerical value manual control equipment movement distance.
Drawings
FIG. 1 is a schematic view of the combination effect of the equipment
In the drawings: the device comprises a support 1, an equipment holder 2, a guide rail 3, a pulley 4, a scale 5, a counterweight steel column 6 and a connecting line 7.
Detailed Description
The utility model is further described by taking a coal seam drilling simulation test with a constant thrust as an example in combination with the attached drawings as follows:
the electric hand drill comprises seven parts including a support (1), an equipment holder (2), a guide rail (3), pulleys (4), a scale (5), a counterweight steel column (6) and a connecting wire (7), the type of the electric hand drill can be replaced within the range supported by the equipment holder (2) according to actual needs, the maximum holding inner diameter of the equipment holder (2) is 60mm, the connecting wire (7) is fixed in the guide rail (3) with the inner diameter of the holder by friction and is made of aluminum alloy, the length of the connecting wire is 600mm, the width of the connecting wire is 110mm, the bottom of the equipment holder (2) is provided with a screw hole, the connecting wire is controlled in a guide groove of the guide rail (3) by a screw rod and a nut which shows smoothness, the adopted pulley (4) is an all-steel pulley special for a 0638 UU-type guide rail, the inner diameter is 6.5mm, the outer diameter is 36.5mm, the scale is adhered to the end of the guide, 3kg, 6kg and 9kg of steel columns are selected as the counterweight steel column (7), and a plurality of steel columns can be connected in series for use if higher requirements are required. The connecting wire (7) has tensile strength not lower than 500N and is not stretchable; the bracket (1) is made of cast iron, and the height of the bracket is 530 mm; the guide rail (3) is adhered to the bracket (1) through metal glue. After this invariable push-pull power device was built and is accomplished, the equipment centre gripping that will need is good, draws connecting wire (7) with the tensiometer and makes equipment keep uniform motion, measures the frictional force size that this equipment corresponds after, fixes counter weight steel column (6) on connecting wire (7), and the fixed power of different demands can be applyed to adjustment steel column weight, advances the chi according to scale (5) numerical value manual control electric drill, can realize simulating the coal seam with invariable thrust unidirectional movement and advance the experiment.
Claims (1)
