Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, and many specific details are set forth in the following description so as to provide a thorough understanding of the present invention. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Without prejudice to the content of the invention, these improvements still belong to the scope of protection claimed by the invention.

The first embodiment is as follows: referring to fig. 1, a traction driving pile driver according to an embodiment of the present invention includes a main pile frame 1, a traction mechanism, a hammer releasing device, and a hammer body 207. The main pile frame 1 is provided with a first pile chamber and a second pile chamber which are longitudinally separated. The traction mechanism comprises a traction sheave 201, a pulley block 202, a traction rope 206 and a traction counterweight 204, wherein the traction counterweight 204 is arranged in the second pile chamber and is connected with the side part of the second pile chamber in a sliding way. The traction sheave 201 is installed on the top of the main pile frame 1, the traction rope 206 is wound around the traction sheave 201 and the pulley block 202, and one end of the traction rope 206 is connected with the traction counterweight 204. The hammer body 207 and the hammer removing device are arranged in the first pile chamber and are connected with the side part of the first pile chamber in a sliding mode. The other end of the hauling rope 206 is connected with a hammer-off device, the hammer body 207 is arranged below the hammer-off device, and the hammer body 207 can be connected with or disconnected from the hammer-off device.

Alternatively, the traction sheave 201 may be mounted on the bottom of the main pile frame 1 (not shown) for easy maintenance.

The traction driving pile driver comprises three processes of lifting the hammer, releasing the hammer and striking the pile, which are mutually matched. During the hammer lifting process, the hammer body 207 and the hammer removing device move upwards along the side part of the first pile chamber under the traction of the traction rope 206 until the hammer body 207 and the pile pipe 106 move to a proper height, so that a preset height difference is kept between the hammer body 207 and the pile pipe 106; at the same time, the traction weight 204 moves in the opposite direction along the side of the second pile chamber, lowering it into position. In the process of removing the hammer and striking the pile, after the hammer body 207 moves to a preset height, under the action of the hammer removing device, the hammer body 207 is separated from the hammer removing device and rapidly falls down to strike the pile pipe 106 under the action of self gravity, so that the pile pipe 106 sinks; during the process of dropping the hammer body 207 and dropping the pile, the hammer dropping device also drops rapidly. After the hammer body 207 finishes the pile striking action, the hammer body 207 is connected with a hammer removing device, and the hammer body 207 and the hammer removing device are driven by a traction machine to be lifted to a proper height; at the same time, the traction weight 204 moves in the opposite direction and descends to a predetermined position. After the hammer lifting action is completed, the above-described hammer removal and pile driving actions are repeated until the pile tube 106 is driven into the ground. In this way, the weight of the hammer body 207 is balanced by the traction weight 204, so that the energy consumption for lifting the hammer can be reduced, the weight of the hammer body 207 can be increased, and the energy for the hammer body 207 to strike the pile can be increased. In the pile driving process, the hammer body 207 is separated from the constraint of the traction counterweight 204 through the hammer separating device, so that the potential energy of the hammer body 207 can be increased, and the pile driving energy can be increased. Moreover, the traction driving pile driver has the advantages of energy saving, low noise, energy saving, environmental protection and the like, thereby being capable of replacing the existing pile driving devices such as a steam hammer, a diesel hammer, a hydraulic hammer and the like and being generally used in urban and rural construction. In addition, the traction mechanism is simple in structure, existing spare and accessory parts are available in the market and are installed in a matched mode with the steel structure main pile frame 1, the overall weight is light, and the production cost is low.

In one embodiment, referring to fig. 2, the main pile frame 1 includes four upright posts a11, two center upright posts a12, two or more long cross beams a13, two or more side beams a14, two or more center beams a15, and two or more short cross beams a16, and four upright posts a11 are symmetrically erected at four corners of the main pile frame 1. Two columns a11 are connected longitudinally by two or more side members a14 at the left or right side of the main pile frame 1. The upper part and the lower part of two upright posts A11 are respectively transversely connected through a long cross beam A13 at the front side part and the rear side part of the main pile frame 1, two ends of two middle upright posts A12 are oppositely and vertically arranged at the middle part of the long cross beam A13, two middle upright posts A12 are respectively transversely connected with the upright posts A11 adjacent to the left and the right through more than two short cross beams A16, and the middle upright posts A12 are longitudinally connected through more than two middle cross beams A15; or, two central uprights a12 are symmetrically arranged between the two uprights a11 at the front side and the rear side of the main pile frame 1, the two central uprights a12 are transversely connected with the adjacent left and right uprights a11 through more than two short cross beams a16, and the central uprights a12 are longitudinally connected through more than two central beams a 15. The center sill A15 divides the main pile frame 1 and encloses a first pile chamber and a second pile chamber. In this way, the main pile frame 1 having the first pile chamber and the second pile chamber is obtained, and the main pile frame 1 has a strong crosswind resistance.

Alternatively, the above-mentioned column a11, center column a12, long beam a13, side beam a14, center beam a15 and short beam a16 are steel pipes, and the steel pipes are connected in the above-mentioned manner to obtain the main pile frame 1 having the first pile chamber and the second pile chamber. Of course, in other embodiments, the main pile frame 1 may also be a tubular body having a first pile chamber and a second pile chamber, for example, the main pile frame 1 is obtained by performing girth welding on a steel plate.

Further, referring to fig. 1 and 2, the traction driving pile driver further comprises at least two guide rails a101 and at least two guide rails B102, wherein the guide rails a101 are oppositely and vertically fixed on the side beam a14 and the middle beam a15 of the first pile chamber respectively; alternatively, the guide rail a101 is fixed to the side beam a14 and the center beam a15 of the first pile chamber so as to face each other and be perpendicular to each other via the guide rail bracket 103. The guide rail B102 is oppositely and vertically fixedly arranged on a side beam A14 and a middle beam A15 of the second pile chamber respectively; alternatively, the guide rail B102 is fixed to the side beam a14 and the center beam a15 of the second pile room through the guide rail bracket 103 in a manner of being opposed to each other and perpendicular to each other. The hammer body 207 and the hammer removing device are slidably connected to the guide rail a101, and the hoisting weight 204 is slidably connected to the guide rail B102 via a weight carriage 205. In this way, the guide rails a101 and B102 can function as guides to ensure that the hammer 207 and the traction weight 204 can be lifted and lowered smoothly in the vertical direction.

Referring to fig. 2, the number of the guide rails a101 and B102 may be set according to actual requirements, and the number of the guide rails a101 and B102 is not limited herein.

In one embodiment, referring to fig. 1, 4 and 5, the destroking device is an electromagnetic destroking device. Specifically, the electromagnetic hammer removing device comprises a hanging bracket 212 and an electromagnet 216 connected with a power supply, wherein the electromagnet 216 is connected with the hanging bracket 212 in an insulated mode, the hanging bracket 212 is connected with the side portion of the first pile chamber in a sliding mode, and one end of the hoisting rope 206 is connected with the hanging bracket 212. The traction driving pile driver also comprises a hammer body sliding frame 208, a hammer body 207 is arranged on the hammer body sliding frame 208 and is in sliding connection with the side part of the first pile chamber through the hammer body sliding frame 208, and the hammer body 207 is in electromagnetic fit with an electromagnet 216. Specifically, the hanger 212 and the hammer carriage 208 are slidably connected to the guide rail a101, respectively, the electromagnet 216 is slidably connected to the guide rail a101 through the hanger 212, and the hammer 207 is slidably connected to the guide rail a101 through the hammer carriage 208.

When the electromagnetic hammer removing device is used, the electromagnet 216 is powered on and sucks the hammer body 207 in the process of lifting the hammer. The hammer 207 and the electromagnet 216 move upward under the traction of the hoist rope 206 until a predetermined height is reached. After the hammer 207 reaches the preset height, the power supply of the electromagnet 216 is cut off, so that the hammer 207 is separated from the restraint of the electromagnet 216, and the hammer 207 rapidly falls under the action of self gravity and strikes the pile pipe 106, so that the pile pipe 106 sinks. During the process of dropping the hammer body 207 and dropping the pile, the hammer dropping device also drops rapidly. After the hammer 207 has completed the pile driving action, the above-described hammer lifting, hammer releasing and pile driving actions are repeated again until the pile tube 106 is driven into the ground. The traction weight 204 moves in a reverse direction in the second pile chamber during hammer lifting, hammer removal and pile driving.

Of course, in other embodiments, the hammer relieving device may also be a mechanical hammer relieving device. Referring to fig. 11 and 12, the mechanical de-hammering device further includes a hook 211, a hanger 212, a hanger cross tube 213, an elastic member 214, and a stopper frame 220. The hanger 212 is slidably connected to a side portion of the first pile chamber, the hanger horizontal tube 213 is fixedly installed at the hanger 212, and the hanger horizontal tube 213 and the hanger 212 are hung at the first pile chamber through the hoist rope 206. The hook 211 is movably arranged on the hanger transverse tube 213, and the hook 211 is used for hooking the hammer body 207. The elastic member 214 has one end connected to the hook 211 and the other end connected to the hanger 212. The stopping frame 220 is disposed above the hook 211, and when the hook 211 abuts against the stopping frame 220, the hook 211 rotates to separate the hook 211 from the hammer 207. Further, the mechanical hammer removing device further comprises a reinforcing plate 215, and the reinforcing plate 215 is disposed on the hook 211, so that the hook 211 is effectively prevented from being deformed.

When the mechanical hammer removing device is used, the hook 211 hooks the hammer body 207 during the hammer lifting process, and the hammer body 207 is lifted to a proper height under the driving of the traction machine and the traction of the traction rope 206, so that the hammer body 207 and the pile pipe 106 are kept at a preset height difference. After the hammer 207 is lifted to a certain height, the hook 211 abuts against the stop frame 220, and the hook 211 is movably arranged on the hanger transverse tube 213, so that under the action of the stop frame 220, the hook 211 rotates and is separated from the hammer 207, and the hammer removing action is realized. After the hammer is removed, under the action of the elastic part 214, the hook 211 rotates reversely and returns to the original state, so that after the hammer body 207 finishes the pile striking action, the hook 211 can hook the hammer body 207 again and drive the hammer body 207 to move to a proper height, and the hammer lifting action is finished again.

Optionally, the elastic member 214 is a spring; alternatively, the elastic member 214 is a steel plate having elasticity. Of course, in other embodiments, the elastic member 214 may be other members having the same function.

Note that the counterweight forces experienced by the traction weight 204 before and after de-weighting are very different. The weight of the hanger 212 and the electromagnet 216 after the removal of the weight is small, and it is necessary to increase the wrap angle between the hoist rope 206 and the traction sheave 201 in order to prevent the hoist rope 206 and the traction sheave 201 from slipping due to insufficient traction force when the weight is lowered to lift the weight. There are two ways to increase the wrap angle: firstly, as shown in fig. 1, two pulleys 209 are arranged in a straight line or an inverted triangle with the traction sheave 201, and secondly, the existing traction sheave is improved into a reel type traction sheave.

In one embodiment, as shown in fig. 10, the traction mechanism further includes a traction motor 221, splines 222, nose 223, and a traction frame 224. The traction sheave 201 is drivingly connected to the traction motor 221 through a spline 222. The traction sheave 201 is provided with a spiral rope groove adapted to the traction rope 206, and the nose 223 is fixedly installed on the traction frame 224 and engaged with the spiral rope groove of the traction sheave 201. It is understood that the traction sheave 201 is drivingly connected to the traction motor 221 through the spline 222 so that the traction sheave 201 can either rotate with the traction motor 221 or slide on the spline 222. Thus, the traction rope 206 is wound on the rope groove of the traction sheave 201, when the traction motor 221 rotates, the traction motor 221 drives the traction sheave 201 to rotate together, and the traction sheave 201 slides leftwards or rightwards along with the protrusion 223, so that the two ends of the traction rope 206 can be always kept in a hanging state with the traction counterweight 204 and the hanger 212, thereby reducing the abrasion of the traction rope 206 and prolonging the service life of the traction rope.

In one embodiment, referring to fig. 1 and 3, the traction drive pile driver further includes a controller, a weight sensor 218, and a magnetic strip 219, the magnetic strip 219 being provided at the side of the second pile chamber.

The weight sensor 218 is electrically connected to the controller and the hoisting mechanism is controlled by the controller's signal. Specifically, the magnetic stripe 219 is directly provided to the side beam a14 of the second pile housing; alternatively, the magnetic strip 219 is provided to the side member a14 of the second pile chamber via the rail bracket 103. Thus, the on-off time of the electromagnet 216 and the hammer lifting, hammer releasing and pile striking strokes of the hammer body 207 can be preset in the controller; in the actual working process, the controller realizes the automatic control of the working process of the hammer body 207 according to the position information provided by the traction counterweight 204 and the encoder. Therefore, the traction driving pile driver can be suitable for different working conditions and working environments to replace pile drivers of different specifications and models, and therefore, one machine has multiple purposes.

movable hoops

111 and 112. Thus, in the pile driving process, the buffer ring 113 can play a buffer role, and the pile tube 106 can be effectively prevented from being damaged.

In one embodiment, the rear side of the main pile frame 1 is provided with a hook, and the main pile frame 1 can be hung on a crawler-type pile driver through the hook for independent use, so that the main pile frame can be called a single-hanging type traction driving pile driver.
