Description

Technical Field

The gate is an important component of the gate valve. Its function is to closely contact the valve seat when the valve is closed to prevent the fluid from passing through. In order to ensure that the gate can effectively seal and extend its service life, it is usually necessary to grind the gate.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-10 The present application is further described in detail.

[0032] See also Figure 1 The grinding mechanism 5 includes a side frame 51 installed on the front end surface of the vertical plate 4. The upper and lower end surfaces of the side frame 51 are provided with slide grooves 52 extending along the length direction thereof. The front end surface of the side frame 51 is provided with a plurality of groups of fixing components 53. The fixing components 53 are evenly arranged along the length direction of the slide grooves 52. The slide grooves 52 on the upper and lower end surfaces of the side frame 51 are internally provided with pressing components 54 matched with the plurality of groups of fixing components 53. The front end surface of the side frame 51 is fixedly provided with a grinding component 55 for grinding the gate plate.

[0033] See also Figure 1 , Figure 4 and Figure 5 The fixing assembly 53 includes a fixing rod 531 symmetrically arranged on the front end surface of the side frame 51, and a rectangular groove 532 penetrating in the left and right directions is arranged on the front end surface of the fixing rod 531. A clamping block 533 that moves up and down is arranged inside the rectangular groove 532. The clamping block 533 is connected to the fixing rod 531 through a spring, and one end of the clamping block 533 located inside the fixing rod 531 is provided with a roller that cooperates with the pressing assembly 54; the other end of the clamping block 533 is arranged as an arc surface structure that cooperates with the gate plate.

[0034] See also Figure 1 , Figure 3 , Figure 4 and Figure 5The pressing assembly 54 includes a hollow guide cylinder 541 arranged inside the slide groove 52, and a push rod 542 is sleeved inside the hollow guide cylinder 541, wherein the sleeve cooperation between the hollow guide cylinder 541 and the push rod 542 can guide the movement of the push rod 542, and an electric telescopic rod 543 is installed on the side wall of the slide groove 52 opposite to the hollow guide cylinder 541, and the telescopic end of the electric telescopic rod 543 is connected to the end close to the push rod 542; the circumferential outer wall of the push rod 542 is evenly fixed with a linkage clamping plate 544 along its length direction, and the side wall of the linkage clamping plate 544 is provided with an inclined block 545 that cooperates with the roller on the clamping block 533, the inclined surface of the inclined surface block 545 cooperates with the roller, and the inclined surface part is provided with a roller guide groove.

[0035] When the gate plates to be polished are pushed into the position of the polishing mechanism 5 along the guide block 322 in sequence, all the gate plates to be polished are located between the upper and lower clamping blocks 533 at the corresponding positions, and then the electric telescopic rod 543 is retracted to pull the push rod 542 to move, further driving all the linkage clamping plates 544 and the inclined block 545 at the upper end to move toward the fixed rod 531. During the movement of the inclined block 545, its inclined surface cooperates with the roller to drive the two clamping blocks 533 opposite to each other, thereby completing the clamping and fixing of the gate plates between the two. The roller guide groove cooperates with the roller to further guide the movement of the inclined surface block 545. Secondly, the cooperation between the roller and the inclined surface can reduce the friction of the inclined surface block 545 and improve its smoothness of movement. The arc surface structure on the two clamping blocks 533 that cooperates with the gate plate clamps the gate plate at one end to improve its ability to fix the gate plate. The side wall bidirectional clamping method set by the present invention can also utilize the structural shape of the gate plate itself for stable locking without affecting the grinding of the gate plate grinding surface, thereby ensuring stable clamping, avoiding shaking of the gate plate during grinding, and improving the grinding effect of the gate plate.

[0036] See also Figure 1 , Figure 3 and Fig.10The grinding assembly 55 includes a driving cylinder 551 installed on the rear end face of the side frame 51, and the telescopic end of the driving cylinder 551 is connected to a rack 552, and the rack 552 is slidably installed on the front end face of the side frame 51. A U-shaped frame 553 is fixedly installed on the front end face of the side frame 51. The U-shaped frame 553 is evenly provided with screw rods 554 along its length direction through bearings. The thread directions of two adjacent screw rods 554 are opposite, and one end of the screw rod 554 is provided with a gear 555 meshing with the rack 552; the rotation directions of the two adjacent screw rods 554 are opposite; the upper and lower sides of each screw rod 554 are Guide rods 556 are symmetrically arranged, one end of which passes through the U-shaped frame 553 and is fixed to the front end surface of the side frame 51, and a connecting plate 557 is commonly arranged between the other end of the spiral screw 554 and the corresponding ends of the two guide rods 556; a grinding module 558 is threadedly arranged on the spiral screw 554, and the grinding module 558 is slidably connected to the guide rod 556 at the corresponding position; the grinding modules 558 on two adjacent spiral screws 554 are staggered front and back; a matching bevel groove is opened at the front end of the guide rod 556, and the directions of the matching bevel grooves on the guide rods 556 on the upper and lower sides of the spiral screw 554 are opposite.

[0037] When the grinding module 558 is controlled to fit with the gate surface and move back and forth for grinding, the reciprocating motion of the driving cylinder 551 drives the rack 552 to move back and forth, and the reciprocating motion of the rack 552 drives the gear 555 to rotate back and forth, further driving the screw rod 554 to rotate back and forth, and due to the sliding fit between the guide rod 556 and the grinding module 558, the guide rod 556 can be used to control the grinding module 558 to move back and forth when the screw rod 554 rotates back and forth; the movement of the driving cylinder 551 is divided into two intervals. When moving in the first interval, the grinding module 558 will be driven to reciprocate, but the grinding module 558 will not exceed the matching bevel position at the front end of the guide rod 556. When the driving cylinder 551 moves to the second interval, the grinding module 558 will exceed the matching bevel position at the front end of the guide rod 556, so that the grinding module 558 cooperates with the matching bevel, and the grinding module 558 is controlled to separate from the gate surface.

[0038] By staggering the grinding modules 558 on both sides of the same gate plate front and back, the stability of the grinding modules 558 during the grinding process of the gate plate can be improved. By applying force obliquely and symmetrically on both sides, the force exerted by the grinding modules 558 on the gate plate can be prevented from causing deformation of the gate plate, thereby further improving the effect of grinding the gate plate.

[0039] See also Figure 1 , Figure 6 , Figure 7 and Figure 8The grinding module 558 includes a grinding frame 5581, which is threadedly arranged on the spiral screw 554, and the grinding frame 5581 is slidably matched with the guide rod 556. Two mutually connected mounting cavities 5582 are arranged on the left and right sides of the grinding frame 5581. The upper and lower side walls of the mounting cavity 5582 are both provided with limit columns 5583. The limit columns 5583 are sleeved with sliding sleeves 5584, and a spring sleeved on the outer wall of the limit columns 5583 is arranged between the sliding sleeve 5584 and the cavity wall of the mounting cavity 5582. The upper and lower sliding sleeves 5584 are pressed against each other. A clamping block 5585 is provided at the near end by means of sliding cooperation, a ball is provided at the end where the two clamping blocks 5585 are close to each other, and a spring is provided between the clamping block 5585 and the sliding sleeve 5584, and the spring is in a compressed state, a steel wire rope 5586 is provided at the end where the two clamping blocks 5585 are far away from each other, and the steel wire rope 5586 is connected to a limiting ball 5587 after passing through the sliding sleeve 5584, and the upper and lower cavity walls of the installation cavity 5582 are provided with fold line grooves 5588, and the limiting ball 5587 is slidably arranged inside the fold line groove 5588.

[0040] See also Figure 6 , Figure 8 and Fig.10 Two L-shaped slides 5589 are symmetrically arranged in the middle part of the grinding frame 5581 by sliding. The horizontal section of the L-shaped slide 5589 is provided with a square groove. A push rod 5590 with a ball at one end is arranged inside the square groove. The push rod 5590 cooperates with the matching inclined groove at the front end of the guide rod 556. The vertical section of the L-shaped slide 5589 is clamped and installed with a grinding block 5591. The upper and lower ends of the grinding block 5591 are clamped and matched with the clamping block 5585.

[0041] When the driving cylinder 551 moves to the second section, the grinding module 558 passes over the matching bevel groove at the front end of the guide rod 556, and the push rod 5590 cooperates with the matching bevel groove. Since the spring always has a pulling force on the sliding sleeve 5584 in the direction of the guide rod 556, the L-shaped slide plate 5589 drives the grinding block 5591 to retract into the grinding frame 5581. During the retraction process, the waste chips on the outer wall of the grinding block 5591 can be scraped against the outer wall of the grinding frame 5581, and the contraction movement of the grinding block 5591 can produce The vibration is conducive to the falling of waste chips on the outer wall of the grinding block 5591, thereby improving the subsequent grinding effect of the grinding block 5591; similarly, the reverse movement of the above process can drive the grinding block 5591 to fit the grinding surface of the gate plate; as the grinding block 5591 continues to retract into the grinding frame 5581, the limiting ball 5587 moves along the horizontal section of the folding groove 5588 to the inclined section, and the steel wire rope 5586 will pull the clamping block 5585 out of the grinding block 5591, thereby facilitating the regular replacement of the grinding block 5591.

[0042] During the specific operation, the gate plate to be polished is first pushed to between the upper and lower clamping blocks 533 at the corresponding positions through the guide block 322 in turn, and then the clamping blocks 533 are controlled to approach each other through the pressing assembly 54 to complete the clamping and limiting of the gate plate. Finally, the two end faces of the gate plate are polished simultaneously through the polishing module 558, and the waste chips during the polishing process are collected through the dust collecting box 2.
