Description

Technical Field

[0001] The utility model relates to the technical field of bluestone mining auxiliary devices, in particular to an anchor stone prying device. Background Art

[0002] Anchor stones are generally mined bluestone, and after cutting, they weigh 1.5 to 2.0 tons. The anchor stones are placed in a messy manner, and there are no lifting points on the anchor stones. They cannot be directly lifted by a crane and need to be tied before they can be lifted or transported. When tying the anchor stone, the anchor stone needs to be lifted slightly so that the rope can extend into the underside of the anchor stone. Due to the lack of a special prying device suitable for the field environment, it can only be pried manually using a steel chisel. The torque is small, and sometimes it takes the joint efforts of multiple people to complete it. In addition, in order to keep the anchor stone lifted, the operator needs to continue to exert force, which is too labor-intensive. In addition, if the anchor stone slips due to unstable center of gravity when it is pried up, it is often difficult for the operator who is holding the steel chisel to exert force to evacuate in time, and there is a risk of personal injury. Utility Model Content

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] This utility model refers to Figure 1-7 .

[0038] The utility model provides an anchor stone prying device, comprising a base 1, a jack 2 being provided on the base 1, a prying seat 3 being provided on the upper end of the jack 2, one end of the prying seat 3 extending to one side of the bottom of the jack 2 and provided with a fork shovel 4, a push rod 5 being further provided on the prying seat 3, one end of the push rod 5 being oriented in the same direction as the fork shovel 4; a support leg 6 being further provided on the side of the base 1 opposite to the fork shovel 4.

[0039] principle:

[0040] During use, the base 1 is placed on one side of the anchor stone. Under the action of the legs 6, the base 1 tilts slightly toward the anchor stone. The jack 2 is placed on the anchor stone, and the fork shovel 4 is inserted into the gap between the lower side of the anchor stone and the soil layer or into the shallow soil layer, with the ram 5 contacting one side of the anchor stone. At this point, the jack 2 can be raised, and the fork shovel 4 lifts the anchor stone. The torque exerted by the fork shovel 4 on the jack 2 is directed toward the anchor stone. At the same time, one side of the anchor stone provides support for the ram 5, and the torque exerted by the ram 5 on the jack 2 is directed away from the anchor stone. As a result, the torque exerted on the jack 2 from the fork shovel 4 and the torque exerted on the ram 5 are balanced, preventing the jack 2 from tipping over. During the slight tilting and rising process of the jack 2, since the prying seat 3, fork shovel 4 and other structures generally have a certain degree of deformation capacity, the jack 2 can also slide slightly relative to the base 1. Therefore, the contact of the ram 5 with the anchor stone has a slight yield, and the contact stress will not increase indefinitely.

[0041] By adopting the utility model, the prying seat 3 is driven by operating the jack 2, and the prying seat 3 drives the fork shovel 4, so that the anchor stone is pried. The operation is convenient, the labor intensity is low, and the safety of the anchor stone prying operation is improved; the support legs 6 keep the base 1 and the jack 2 slightly tilted, which ensures that the top rod 5 is in close contact with the side of the anchor stone, the top rod 5 abuts against one side of the anchor stone, and the torques of the top rod 5 and the fork shovel 4 on the jack 2 are balanced with each other, which avoids the jack 2 from tipping over and improves safety; at the same time, the support legs 6 and the base 1 achieve reliable support for the bottom of the jack 2, the bottom of the jack 2 is evenly stressed, and the reliability is good.

[0042] Further, such as Figure 1-4 As shown: an internal thread seat 7 is provided on the top of the prying seat 3, and the push rod 5 is connected to the internal thread seat 7 through an external thread; a hand-held plate 8 is provided at the other end of the push rod 5.

[0043] By rotating the hand-held plate 8, it is convenient to adjust the length of the top rod 5 extending toward the anchor stone, and at the same time it can adapt to the length of the fork shovel 4 extending under the anchor stone, with good flexibility.

[0044] Furthermore, a cylindrical head 9 is provided at one end of the push rod 5 .

[0045] When in use, a groove can be made on the anchor stone, and the cylindrical head 9 is inserted into the groove of the anchor stone, so that the top rod 5 and the fork shovel 4 jointly bear the weight of the anchor stone, thereby improving the bearing capacity.

[0046] Furthermore, the prying seat 3 is in an inverted L-shape, the upper part of the prying seat 3 extends to the top of the jack 2 and is fixedly connected to the jack 2, and the lower end of the prying seat 3 is integrally connected to the fork shovel 4.

[0047] Note: In one piece, the prying seat 3 and the fork shovel 4 are made of the same blank and processed by forging, cutting, etc. Preferably, the upper part of the prying seat 3 is welded to the jack 2.

[0048] The structure has high strength, long service life and good stability.

[0049] Furthermore, springs 10 are provided on both sides of the upper portion of the prying seat 3 , and the lower end of the spring 10 is connected to the bottom of the jack 2 .

[0050] When the operation is completed and the device is recovered, after the anchor stone touches the ground, the jack 2 continues to retract under the action of the spring 10, and the resetting efficiency of the jack 2 is high.

[0051] Further, such as Figure 1-7 As shown, a bottom plate 11 is provided at the bottom of the jack 2 , and first limit blocks 13 are provided on the base 1 at positions on opposite sides of the bottom plate 11 .

[0052] The bottom plate 11 improves the stability of the jack 2, and the jack 2 is not easy to tip over; the first limit block 13 is used to prevent the jack 2 from sliding in a direction perpendicular to the fork shovel 4, thereby improving safety.

[0053] Furthermore, a notch 12 is provided on one side of the bottom plate 11 , and the fork shovel 4 is located in the notch 12 .

[0054] The fork shovel 4 and the bottom plate 11 are prevented from interfering with each other, ensuring that the fork shovel 4 can smoothly extend into the lower side of the anchor stone during use.

[0055] Further, such as Figure 1 、 5 -7: The base 1 is further provided with a second limit block 14, and the second limit block 14 and the fork shovel 4 are located on opposite sides of the bottom plate 11; the second limit block 14 and the first limit block 13 are provided with a slot for the edge of the bottom plate 11 to enter on the side close to the bottom plate 11.

[0056] When the jack 2 slides away from the anchor stone, the bottom plate 11 can be locked into the slots between the second limit block 14 and the first limit block 13, thereby preventing the jack 2 from excessive sliding and shaking and improving safety.

[0057] Furthermore, one side of the bottom plate 11 is an isosceles trapezoid, and the direction of the short base of the trapezoid is opposite to the extension direction of the fork shovel 4; at least two third limit blocks 15 are also provided on the base 1, and the trapezoidal portion of the bottom plate 11 is located between the two third limit blocks 15.

[0058] The two third limiting blocks 15 cooperate with the first limiting block 13 to prevent the jack 2 from rotating horizontally, thereby improving safety.

[0059] Furthermore, the support leg 6 includes a screw rod, which passes through the base 1 and is provided with two nuts 16, which are respectively located on the upper and lower sides of the base 1; the lower end of the screw rod is also provided with a chassis 17, and the screw rod and the chassis 17 are hinged by a ball head; the support leg 6 is provided with two.

[0060] By cooperating with the screw and the two nuts 16, it is convenient to adjust the height of one side of the base 1, thereby adjusting the inclination of the jack 2, with good flexibility; the chassis 17 is set by the ball head hinge to ensure that the chassis 17 fits closely with the ground, avoiding the sliding of the support legs 6, and having good stability.
