The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 3, a slip limiting device 110 of the present application is used for being installed between a push beam 120 and a boom carriage 130 of a construction machine to limit the sliding direction of the push beam 120 of the construction machine relative to the boom carriage 130 of the construction machine. Specifically, the sliding direction of the push beam 120 is along the length direction of the boom carriage 130.
In a specific embodiment, the slip limiting device 110 comprises a fixing member 111, the fixing member 111 being adapted to be fixedly connected to the boom carriage 130 of the work machine. The term "fixed connection" as used herein refers to a connection in which two objects are fixedly connected to each other by a bolt or by welding or the like so that the two objects cannot move relative to each other. The fixing member 111 is formed with a limit groove 1111 with an opening 1132 at one end, so that at least a part of the propelling beam 120 of the engineering machine is embedded into the fixing member 111 from the opening 1132 end of the limit groove 1111, that is, the beam body of the propelling beam 120 extends into the limit groove 1111.
Specifically, the limiting groove 1111 penetrates the fixing member 111 along the first straight line C1, so that the push beam 120 of the construction machine can slide along the first straight line C1 with respect to the fixing member 111. The first straight line C1 is parallel to the length direction of the boom carriage 130, i.e., the direction of the limit groove 1111 restricts the push beam 120 from sliding along the length direction parallel to the boom carriage 130.
More specifically, the fixing member 111 is provided with a first limiting portion 1112 and a second limiting portion 1113 at two sides of the opening 1132 of the limiting slot 1111 to limit the sliding of the pushing beam 120 of the engineering machine located between the first limiting portion 1112 and the second limiting portion 1113 along the direction of the second straight line C2 perpendicular to the first straight line C1. The first limiting portion 1112 is an upper inner surface of the limiting groove 1111, and the second limiting portion 1113 is a lower inner surface of the limiting groove 1111, so that when an upper surface of the beam body of the push beam 120 contacts with the upper inner surface of the limiting groove 1111, a lower surface of the beam body of the push beam 120 contacts with the lower inner surface of the limiting groove 1111, the push beam 120 cannot move along the second straight line C2 perpendicular to the first straight line C1.
The fixing piece 111 is fixedly arranged on the large arm sliding frame 130, the limiting groove 1111 is formed in the fixing piece 111, the push beam 120 can only move along the length direction of the large arm sliding frame 130, meanwhile, the first limiting part 1112 and the second limiting part 1113 are arranged on two sides of the opening 1132 end of the limiting groove 1111, so that the push beam 120 body cannot move along the direction of the second straight line C2 perpendicular to the direction of the first straight line C1, and therefore when the large arm sliding frame 130 drives the push beam 120 to perform multi-gesture operation, the accuracy of the push beam 120 in operation is ensured, and meanwhile, the push beam 120 can be prevented from falling off from the large arm sliding frame 130 in operation.
In a specific embodiment, the slip limiting device 110 further comprises contacts 112, the contacts 112 being fixedly mounted in the limiting slots 1111, wherein at least one of the contacts 112 is fixedly connected to the first limiting portion 1112; at least one contact 112 is fixedly connected to the second spacing portion 1113; the contact 112 connected to the first stopper 1112 is spaced apart from the contact 112 connected to the second stopper 1113.
The first limiting portion 1112 and the second limiting portion 1113 are fixedly connected with the contact 112, and the contact 112 is fixed in the limiting groove 1111 in a fixed connection manner, wherein the fixed connection is a connection manner such as a bolt connection, so that the contact 112 and the inner surface of the limiting groove 1111 cannot displace. When the push beam 120 slides in the limit groove 1111, the push beam 120 is worn in direct contact with the contact 112, and the contact 112 is made of nonmetallic materials such as nylon.
The contact 112 on the second limiting portion 1113 further includes a vertical surface 1121 along the second straight line C2, and when the push beam 120 and the contact 112 wear, the beam body of the push beam 120 along the second straight line C2 contacts the vertical surface 1121, so that the beam body of the push beam 120 along the second straight line C2 can be effectively prevented from directly contacting the fixing member 111 to cause wear of the push beam 120.
In a specific embodiment, ultra-high molecular weight polyethylene is used as the material for manufacturing the contact 112, which has high hardness, good wear resistance, and low friction coefficient, and can reduce the resistance of the push beam 120 and the large arm carriage 130, and friction with the steel beam body of the push beam 120, so that the abrasion of the push beam 120 is greatly reduced, and the service life of the push beam 120 is prolonged.
Because the contact 112 and the push beam 120 are worn by direct contact, when the contact 112 is worn seriously after a period of working, the contact 112 needs to be replaced, so that the contact is fixedly connected with the first limiting portion 1112 and the second limiting portion 1113 by bolts so as to be convenient to detach and replace.
In a specific embodiment, the length of the contact 112 is parallel to the first line C1. The surface of the contact 112 connected to the first limiting portion 1112 facing away from the first limiting portion 1112 is a plane. That is, the contact surface of the contact 112 and the push beam 120 is a plane, which ensures that the sliding contact area of the contact 112 and the push beam 120 is the largest, so that the abrasion degree of the contact 112 in a certain service time is the smallest, and the service life of the contact 112 is effectively prolonged.
Likewise, the surface of the contact 112 connected to the second stopper 1113 away from the second stopper 1113 is a plane.
In a specific embodiment, the fixing member 111 includes a first fixing portion 1114 and a second fixing portion 1115, and the first fixing portion 1114 is formed at an end of the first limiting portion 1112 remote from the opening 1132 of the limiting groove 1111; the second fixing portion 1115 is formed at one end of the second limiting portion 1113 away from the opening 1132 of the limiting slot 1111; wherein the first fixing portion 1114 is fixedly connected to the second fixing portion 1115.
Specifically, the first fixing portion 1114 and the second fixing portion 1115 are fixedly connected by the fixing bolt 114, that is, bolt holes are formed in the first fixing portion 1114 and the second fixing portion 1115, and the fixing bolt 114 passes through the bolt holes to fixedly connect the first fixing portion 1114 and the second fixing portion 1115.
More specifically, at least one adjustment shim 113 is provided between the first fixing portion 1114 and the second fixing portion 1115, and the adjustment shim 113 is fixedly mounted between the first fixing portion 1114 and the second fixing portion 1115. The adjustment washer 113 is located outside the limit groove 1111 to prevent the adjustment washer 113 from extending into the limit groove 1111 to cause the feed beam 120 and the adjustment washer 113 to be worn away from each other.
In a specific embodiment, three adjustment shims 113 are disposed between the first fixing portion 1114 and the second fixing portion 1115, and the three adjustment shims 113 are sequentially stacked, when the thickness of the contact 112 gradually decreases due to the abrasion between the contact 112 and the push beam 120, and when the contact 112 is not replaced, the distance between the first fixing portion 1114 and the second fixing portion 1115 can be reduced by reducing the number of adjustment shims 113, that is, the contact 112 fixed on the first limiting portion 1112 and the second limiting portion 1113 is in contact with the push beam 120 again, so as to ensure that the push beam 120 does not move along the second straight line C2.
More specifically, the adjustment pad 113 is provided with a mounting hole 1131.
As shown in fig. 4, in a specific embodiment, the adjusting pad 113 is provided with a plurality of mounting holes 1131, one end of the mounting hole 1131, far away from the limiting groove 1111, of the adjusting pad 113 is provided with an opening 1132, when the number of the adjusting pad 113 needs to be adjusted, the adjusting pad 113 can be taken out without integrally separating the first fixing portion 1114 from the second fixing portion 1115, and only the fixing bolts 114 on the first fixing portion 1114 and the second fixing portion 1115 need to be unscrewed, so that a gap with a certain thickness exists between the first fixing portion 1114 and the second fixing portion 1115, and at this time, the adjusting pad 113 can be taken out from between the first fixing portion 1114 and the second fixing portion 1115.
In a specific embodiment, as shown in fig. 5, the adjusting pad 113 is provided with a mounting hole 1131, the mounting hole 1131 is provided with an opening 1132 at one end of the adjusting pad 113 along the first straight line C1, and when the number of the adjusting pads 113 needs to be adjusted, only the adjusting pad 113 needs to be taken out along the first straight line C1 after the bolts are loosened.
As another aspect of the present application, some embodiments of the present application provide an engineering driller carriage 100, the engineering driller carriage 100 including a push beam 120, the push beam 120 being an actuator for mounting the engineering driller carriage 100 to perform a drilling operation; the engineering driller 100 further comprises a large arm carriage 130, wherein the large arm carriage 130 is slidably connected with the pushing beam 120 to drive the pushing beam 120 to slide along the first straight line C1 direction in operation; the engineering driller 100 also includes the above-mentioned slip limiting device 110; wherein the slip limiting device 110 is disposed between the push beam 120 and the boom carriage 130 to limit the sliding direction of the push beam 120 relative to the boom carriage 130.
