A detection device for installation and adjustment of large equipment

Abstract

The present invention discloses a detection device for installation and adjustment of large equipment. The structure comprises a detection mechanism, an adjustment rotating plate, a support frame and a traction rope. An adjustment rotating plate is arranged on the outer side of the middle end of the detection mechanism. When a laser emitter rotates up and down inside a limit seat, a brush cleans the inner side of the lower end of the limit seat to avoid dust accumulation in the gap between the laser emitter and the limit seat. The flow of the internal air pressure of the extruded tube is accelerated by the extrusion, and the speed of heat flowing out of the heat dissipation hole is accelerated. The laser emitter is adjusted to a suitable height for three-dimensional measurement by rotating the lifting rod inside the spiral tube sleeve. Gravity pressure is generated between the support rod and the support foot, and the telescopic hose generates elastic contraction to squeeze out the air pressure inside the suction cup, thereby ensuring that the suction cup performs vacuum adsorption on the machine room floor, improving the firmness of the support foot, avoiding displacement of the laser emitter during the three-dimensional measurement of the hole center, and improving the accuracy of laser emitter detection.

Description

Technical Field

[0001] The invention relates to the field of large-scale aluminum extruders, and more specifically, to a detection device used for installation and adjustment of large-scale equipment. Background Art

[0002] Extruders are the main equipment for the production of light alloy tubes, rods and profiles. The volume of large aluminum extruders is very large. During the installation of large aluminum extruders, the front and rear beam adjustment detection coordinate system is established by combining horizontal alignment with three-dimensional space measurement, and the center holes of the front and rear beams are accurately adjusted, so that the tension column can be smoothly installed and penetrated into the front and rear beam holes of the large aluminum extruder after being hoisted horizontally. The APIT3 laser tracker LTS-3000 is used for three-dimensional space measurement. However, when the APIT3 laser tracker LTS-3000 measures the three-dimensional space inside the machine room of the large aluminum extruder, the equipment inside the machine room generates a lot of dust due to long-term operation. The dust is easily adsorbed and enters the surface and inside of the laser emitter of the APIT3 laser tracker LTS-3000, which causes the laser emitter to be stuck and the heat dissipation effect to decrease during the rotation process. At the same time, there are many equipment inside the machine room. The APIT3 laser tracker LTS-3000 is easy to be touched during the placement and detection process. If it is touched, a slight position offset will reduce the accuracy of the laser emitter in three-dimensional space detection. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] As attached Figure 1 To Attachment Figure 5 As shown:

[0023] The present invention discloses a detection device for installation and adjustment of large equipment, and its structure includes a detection mechanism 1, an adjustment rotating plate 2, a support frame 3, and a traction rope 4. The detection mechanism 1 is provided with an adjustment rotating plate 2 on the outer side of the middle end, and the adjustment rotating plate 2 is connected to the upper end of the support frame 3. The inner end of the traction rope 4 is fixedly installed on the outer side of the lower end of the detection mechanism 1, and the outer end of the traction rope 4 is fixed to the middle end of the support frame 3. The detection mechanism 1 includes a rotating mechanism 11, a base 12, a motor 13, and a support mechanism 14. The rotating mechanism 11 is located above the base 12, and a motor 13 is provided inside the base 12. The output end of the motor 13 is fixed to the bottom of the rotating mechanism 11, the bottom of the base 12 is connected to the top of the support mechanism 14, and the adjustment rotating plate 2 is provided on the outer side of the upper end of the support mechanism 14, and the inner end of the traction rope 4 is fixedly installed on the outer side of the middle end of the support mechanism 14.

[0024] Among them, the rotating mechanism 11 includes a laser emitter 11a, a rotating shaft 11b, a limit seat 11c, a torsion shaft 11d, a connecting rod 11e, and a brush 11f. The middle end of the outer side of the laser emitter 11a is installed on the inner side of the limit seat 11c through the rotating shaft 11b, and the lower end of the laser emitter 11a is hinged to the upper end of the connecting rod 11e through the torsion shaft 11d. A brush 11f is provided at the bottom of the connecting rod 11e, and the bottom of the brush 11f is in conflict with the bottom of the inner side of the limit seat 11c. The torsion shaft 11d, the connecting rod 11e and the brush 11f are each provided with three, and are equidistantly distributed in an arc shape between the bottom of the laser emitter 11a and the inner side of the lower end of the limit seat 11c. During the angular rotation of the laser emitter 11a, the brush 11f can clean the gap between the laser emitter 11a and the limit seat 11c to avoid the effect of dust on the laser emitter 11a causing jamming during the rotation process.

[0025] The laser transmitter 11a includes a housing a1, a laser a2, a control mainboard a3, a heat sink a4, a push rod a5, and an exhaust mechanism a6. The middle end of the outer side of the housing a1 is installed on the inner side of the limit seat 11c through a rotating shaft 11b, and the lower end of the housing a1 is hinged to the upper end of the linkage rod 11e through a torsion shaft 11d. The front end of the housing a1 is embedded with a laser a2, and the laser a2 is electrically connected to the control mainboard a3. A heat sink a4 is provided on the rear side of the control mainboard a3, and the middle part of the outer end of the heat sink a4 is connected to the inner wall of the housing a1 through a push rod a5. The rear end of the heat sink a4 is in conflict with the exhaust mechanism a6, and the exhaust mechanism a6 is embedded in the rear end of the casing a1. The heat sink a4 is an arc-shaped structure, and the arc center of the heat sink a4 is located at the same point as the control main board a3, ensuring that the heat generated by the control main board a3 can be fully absorbed. There are two top rods a5, and a spring is also provided on the outside to form a spring top rod, which applies elastic force to the upper and lower inner ends of the casing a1 and the upper and lower ends of the outer side of the heat sink a4, so that the heat sink a4 generates elastic displacement in the process of absorbing heat, thereby accelerating the effect of discharging heat.

[0026] The exhaust mechanism a6 includes an extruded tube a61, a heat dissipation hole a62, an opening and closing piece a63, and a spring shaft a64. The front end of the extruded tube a61 is in conflict with the rear end surface of the heat dissipation plate a4, and the rear end of the extruded tube a61 is connected with the heat dissipation hole a62. The heat dissipation hole a62 runs through the rear end of the housing a1. The outer end of the opening and closing piece a63 is hinged to the inside of the heat dissipation hole a62 through the spring shaft a64. The opening and closing piece a63 is in conflict with the rear end of the heat dissipation plate a4. The extruded tube a61 is a pleated structure and is made of rubber. It has a certain resilience, which is beneficial to the sealed heat dissipation connection between the heat sink a4 and the heat dissipation hole a62. At the same time, the air pressure flow inside the squeezed tube a61 is accelerated, which speeds up the heat outflow from the heat dissipation hole a62. There are two opening and closing pieces a63 and two spring shafts a64, which are symmetrically installed up and down. The elastic torsion force applied to the opening and closing pieces a63 by the spring shaft a64 makes the two opening and closing pieces a63 collide with each other to close the inside of the heat dissipation hole a62, thereby preventing external dust from entering the inside of the casing a1 through the heat dissipation hole a62.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In the present invention, the detection mechanism 1 is placed at a suitable position in the machine room, and then a reasonable measurement reference is selected. The main beam on one side of the large aluminum extruder is used as a reference, and the other side beam is detected by the detection mechanism 1. During the placement of the detection mechanism 1, the support frame 3 is opened, and then the traction rope 4 is pulled between the support frame 3 and the support mechanism 14, and the laser emitter 11a is placed at a suitable position for laser three-dimensional measurement. During the measurement process, the laser emitter 11a is driven by the motor 13 to rotate horizontally as a whole, and the rotating shaft 11b drives the laser emitter 11a to rotate up and down, so that the laser emitter 11a performs three-dimensional measurement. During the up and down rotation of the laser emitter 11a on the inner side of the limit seat 11c, the torsion shaft 11d applies elastic torsion to the linkage rod 11e, thereby driving the brush 11f to clean the inner side of the lower end of the limit seat 11c. Sweep to prevent dust from accumulating in the gap between the laser emitter 11a and the limit seat 11c, which may cause jamming during the rotation of the laser emitter 11a. At the same time, the heat generated during the laser measurement of the laser a2 controlled by the control mainboard a3 is fully absorbed by the heat sink a4. At this time, the heat sink a4 elastically displaces on the top rod a5, so that the heat is accelerated to flow to the rear end of the casing a1, and then the heat enters the extruded tube a61. The extruded tube a61 is accelerated by the internal air pressure of the extrusion, which speeds up the outflow of heat from the heat dissipation hole a62. The elastic torsion force applied to the opening and closing piece a63 by the spring shaft a64 causes the two opening and closing pieces a63 to collide with each other to close the inside of the heat dissipation hole a62, thereby preventing external dust from entering the casing a1 through the heat dissipation hole a62, thereby improving the accuracy of the three-dimensional measurement of the hole center by the laser emitter 11a and reducing the measurement error.

[0029] Embodiment 2:

[0030] As attached Figure 6 To Attachment Figure 7 As shown:

[0031] Among them, the supporting mechanism 14 includes a spiral tube sleeve 14a, a lifting rod 14b, a shock-absorbing rod 14c, and an adsorption mechanism 14d. The lower end of the lifting rod 14b is installed inside the upper end of the spiral tube sleeve 14a with a clearance fit and is threadedly connected. The top of the shock-absorbing rod 14c is installed inside the lower end of the spiral tube sleeve 14a with a clearance fit, and the bottom of the shock-absorbing rod 14c is welded to the top of the adsorption mechanism 14d. The top of the adsorption mechanism 14d is installed inside the lower end of the spiral tube sleeve 14a with a clearance fit. The top of the lifting rod 14b is fixed to the bottom of the base 12. The lower end of the lifting rod 14b is provided with an external thread, and the external thread at the lower end of the lifting rod 14b matches the internal thread inside the spiral tube sleeve 14a, ensuring that the lifting rod 14b is spirally rotated inside the spiral tube sleeve 14a, thereby adjusting the height between the lifting rod 14b and the spiral tube sleeve 14a.

[0032] Among them, the adsorption mechanism 14d includes a support rod d1, a telescopic hose d2, a top spring d3, a support leg d4, an air guide hole d5, and a suction cup d6. The top of the support rod d1 is welded to the bottom of the shock-absorbing rod 14c, and the top of the support rod d1 is installed inside the lower end of the spiral tube sleeve 14a with a clearance fit. The lower end of the support rod d1 is connected to the upper end of the support leg d4 through the telescopic hose d2, and a top spring d3 is provided inside the telescopic hose d2. The support leg d4 is penetrated by an air guide hole d5. The bottom of the support leg d4 is provided with a suction cup d6, and the suction cup d6 is connected to the air guide hole d5. The telescopic hose d2 has a pleated structure and is made of rubber with a certain resilience. After being squeezed between the support rod d1 and the support leg d4, the telescopic hose d2 produces elastic contraction, changes the internal air pressure, and thereby squeezes out the air pressure inside the suction cup d6, ensuring that the suction cup d6 is vacuum adsorbed on the machine room floor, improving the firmness of the support of the support leg d4, and avoiding displacement of the detection mechanism 1 during the detection process.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In the present invention, during the placement of the laser emitter 11a, the height between the lifting rod 14b and the spiral sleeve 14a can be adjusted by rotating the lifting rod 14b inside the spiral sleeve 14a, so that the laser emitter 11a is adjusted to a suitable height for three-dimensional measurement. At the same time, the shock-absorbing rod 14c installed between the spiral sleeve 14a and the support rod d1 can ensure that the laser emitter 11a is in a stable state after the height adjustment, avoiding the laser emitter 11a itself from angular deviation. Then, gravity pressure is generated between the support rod d1 and the support leg d4, and at this time, the telescopic hose d2 at the connection between the support rod d1 and the support leg d4 is squeezed, and the telescopic hose d2 produces elastic contraction, changing the internal air pressure, and through the conduction of the air guide hole d5, the air pressure inside the suction cup d6 is squeezed out, ensuring that the suction cup d6 is vacuum-adsorbed on the machine room floor, improving the firmness of the support of the support leg d4, avoiding displacement of the laser emitter 11a during the three-dimensional measurement of the hole center, and improving the accuracy of the detection of the laser emitter 11a.
