Description

Technical Field

[0001] The invention relates to the technical field of counterweight production, and more specifically to a grouting counterweight structure based on the production process of elevator counterweight. Background Art

[0002] In a rope-type elevator, the traction force generated by the friction between the rope and the rope pulley drives the car and the counterweight to move up and down to achieve the purpose of transportation. The counterweight system is used to balance the weight of the car and part of the elevator load weight, which can reduce the output power of the motor to reduce the loss of motor energy. At present, the counterweight block is usually made of a variety of different materials such as the counterweight block frame and filled concrete aggregate;

[0043] It should be noted that the conveying member 13 includes two transmission wheels, one transmission wheel is fixedly connected to the driving shaft 84, and the other transmission wheel is fixedly connected to the driven shaft 91, and the two transmission wheels are connected through a conveyor belt transmission;

[0044] An air release pipe 94 is inserted into the side wall of the air supply box 92, and a control valve 1 is arranged on the outer wall of the air release pipe 94. An air intake pipe is also inserted into the side wall of the air supply box 92, and a one-way valve is arranged on the outer wall of the air intake pipe. External gas enters the air supply box 92 through the air intake pipe and is then discharged through the air delivery pipe 93.

[0045] It should be noted that when the placement rack 12 does not move to the bottom of the feeding pipe 11, the control valve 1 above the air vent pipe 94 is opened, and the control valve 2 above the gas delivery pipe 93 is closed, so that the gas is discharged through the air vent pipe 94;

[0046] An air delivery pipe 93 is inserted into the side wall of the air supply box 92, and a U-shaped pipe 95 is connected to the output end of the air delivery pipe 93. A control valve 2 is arranged on the outer wall of the air delivery pipe 93;

[0047] The conveying member 13 drives the driven shaft 91 to rotate, the driven shaft 91 drives the reciprocating screw to rotate, and the reciprocating screw drives the piston plate 2 to reciprocate intermittently to squeeze the external gas into the gas pipe 93, and then enter the conveying cavity 96 through the gas pipe 93 and the U-shaped tube;

[0048] Both output ends of the U-shaped tube 95 are provided with a vibration assembly, which includes a conveying chamber 96 opened inside the roller conveyor 3, and the output end of the U-shaped tube 95 is connected to the conveying chamber 96. A plurality of sliding chambers 97 are also opened inside the roller conveyor 3, and the plurality of sliding chambers 97 are connected to the conveying chamber 96. A piston plate 98 is slidably arranged inside the sliding chamber 97, and a vibration column 910 is fixedly arranged on the top of the piston plate 98. The vibration column 910 and the sliding chamber 97 are slidably matched. A thrust spring is sleeved on the outer wall of the vibration column 910, and the thrust spring is located between the piston plate 98 and the sliding chamber 97. An exhaust pipe 99 is opened on the inner wall of the roller conveyor 3 on one side of the sliding chamber 97, and the input end of the exhaust pipe 99 is in contact with the piston plate 98, and the input end of the exhaust pipe 99 is located in the middle and upper part of the piston plate 98;

[0049] The gas inside the conveying chamber 96 squeezes the piston plate 98 upward. When the bottom of the piston plate 98 moves to above the input end of the vent pipe 94, the gas inside the conveying chamber 96 leaks out. Since the conveying chamber 96 is intermittently filled with air, the reciprocating motion of the vibration column 910 can be realized, and the frame can be slightly vibrated. In conjunction with the intermittent discharge of the discharge pipe 11, when the slurry is layered, the bubbles in the slurry are discharged through the vibration of the frame, and the slurry is vibrated to level and remove bubbles.

[0050] It can be known from the present invention in combination with Example 1 and Example 2 that the gas inside the conveying chamber 96 presses the piston plate 98 upward to realize the reciprocating motion of the vibration column 910, and cooperates with the slight vibration of the frame to ensure that the slurry is evenly grouted in the frame when the slurry is loaded in layers, and the slight vibration of the frame is simultaneously realized to reduce the bubbles in the slurry. The two cooperate with each other to complete the grouting of the frame, thereby jointly improving the production quality of the counterweight block.

[0051] The working process and principle of the present invention are as follows:

[0052] Step 1: First, install the frame above the placement rack 12, and convey the placement rack 12 through the roller conveyor 3. Before the frame quickly moves to the bottom of the grouting bin 1, start the drive motor so that the drive shaft 84 drives the notched gear 83 to rotate, and the notched gear 83 cooperates with the gear 1 81 to make the connecting shaft 82 rotate intermittently, so as to realize the intermittent rotation of the spiral rod;

[0053] Next, when the frame moves to the bottom of the grouting bucket, the slurry enters the frame through the feed pipe 11. At the same time, the driven shaft 91 is driven to rotate by the conveying member 13, and the driven shaft 91 drives the reciprocating screw to rotate. The reciprocating screw drives the piston plate 2 to reciprocate intermittently to squeeze the external gas into the gas delivery pipe 93, and then enters the delivery chamber 96 through the gas delivery pipe 93 and the U-shaped pipe.

[0054] Step 2: The gas inside the conveying chamber 96 squeezes the piston plate 98 upward. When the bottom of the piston plate 98 moves to above the input end of the vent pipe 94, the gas inside the conveying chamber 96 leaks out. Due to the intermittent inflation into the conveying chamber 96, the piston plate 98 is reset and then moves upward again, thereby realizing the reciprocating motion of the vibration column 910 and slight vibration of the frame. In conjunction with the intermittent discharge of the discharge pipe 11, when the slurry is layered, the bubbles in the slurry are discharged through the vibration of the frame, and the slurry is vibrated to remove bubbles, thereby improving the production quality of the counterweight block.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods.
