Description

Technical Field

[0001] The utility model relates to the technical field of soft foundation hardening, in particular to construction equipment for quickly hardening sandy soft foundation. Background Art

[0002] If the foundation is not strong enough before construction, such as sandy soft foundation, the foundation structure is unstable. In order to prevent accidents such as foundation sinking and cracking after construction, causing building instability, the soft foundation needs to be treated so that its settlement becomes strong enough to improve the consolidation and stability of the soft foundation.

[0003] The existing sandy soft foundation hardening is usually carried out by the dynamic compaction method, which is to use lifting equipment to lift a 10-25 ton hammer to a high place and then let it fall freely. The soft base layer is compacted by relying on the compaction energy and shock wave generated by the gravity of the hammer. Manual control is required to lock and disconnect the lifting component to achieve the fall of the hammer. In addition, some soft foundations need to be hardened multiple times because the impact force generated by the free fall of the hammer is not enough to achieve hardening in one time. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that the locking and disconnection of the lifting assembly are manually controlled to realize the rise and fall of the heavy hammer, and some soft foundations require the heavy hammer to perform free fall operations multiple times.

[0006] 2. Technical Solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a construction equipment for rapid hardening of sandy soft foundation, comprising a heavy hammer, a crane and a lifting arm connected to the crane, the lifting arm being connected to a lifting assembly that can lift the heavy hammer, the free end of the lifting arm being hinged with a hinge rod, the other end of the hinge rod being connected to a connecting shell, the connecting shell being connected with a switch that can open and close the lifting assembly and an acceleration assembly that can increase the acceleration of the heavy hammer's descent, the acceleration assembly comprising a protrusion connected to the top of the heavy hammer, a groove being relatively connected to the bottom end of the connecting shell, the groove cooperating with the protrusion, a lifting plate being slidably connected in the groove, a spring being connected between the lifting plate and the groove, and an opening and closing assembly that can drive the switch to close being connected to the lifting plate.

[0008] Furthermore, the lifting assembly includes a motor connected to the lifting arm and can be locked after power is supplied. The power output end of the motor is connected to a winding wheel, and a pull rope is connected to the winding wheel. The other end of the pull rope passes through the connecting shell and the lifting plate in sequence and is connected to a protrusion at the end. When the heavy hammer is on the ground, by starting the motor, the motor drives the winding wheel to wind the pull rope and then drives the protrusion at the other end to drive the heavy hammer to rise steadily.

[0009] Furthermore, the connecting shell and the middle part of the lifting plate are relatively connected to each other and are provided with a through hole that cooperates with the pull rope. The bottom end of the through hole on the lifting plate is set into a smooth rounded corner, and the matching setting of the through hole facilitates the passage of the pull rope. The heavy hammer may swing during the rising process, and the smooth rounded corner can reduce the friction between the heavy hammer and the pull rope, thereby extending its service life.

[0010] Furthermore, the top end of the connecting shell is rotatably connected to the two sides of the through hole respectively, and the free end of the lifting arm is rotatably connected to the second guide wheel. The pull rope passes through the first guide wheels in turn and is then wrapped around the second guide wheel. The coordinated arrangement of the first guide wheel and the second guide wheel facilitates guiding the direction of the pull rope and also facilitates reducing the friction between the pull rope and the connecting shell and the lifting arm.

[0011] Furthermore, the protrusion is a cylindrical structure, the groove cooperates with the protrusion, and a conical guide groove is connected to the bottom end of the groove. The setting of the conical guide groove facilitates guiding the protrusion to avoid the protrusion from swinging during the rising process and failing to cooperate with the groove.

[0012] Furthermore, the opening and closing assembly includes a cylinder connected to the top of the lifting plate, the other end of the cylinder is connected to a drive ring, the top of the groove is connected to a switch groove for accommodating a switch, the drive ring cooperates with the switch, and the lifting assembly drives the protrusion to rise into the groove. As the protrusion continues to rise, the lifting plate will be driven. The lifting plate driving cylinder drives the drive ring to extend into the switch groove until the drive ring drives the switch to disconnect the circuit of the motor. At this time, the motor is no longer energized and cannot lock the height of the weight, and the weight begins to fall to the ground.

[0013] 3. Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are:

[0015] The lifting component can drive the heavy hammer to lift upward; the acceleration component allows the protrusion on the top of the heavy hammer to drive the lifting plate to slide down during the process of rising into the groove, so that the spring is compressed and stored, so that when the heavy hammer falls, it is not only affected by gravity, but also by the elastic force of the spring reset, thereby increasing the acceleration of the heavy hammer when it falls, enhancing the impact of the heavy hammer on the soft foundation, and accelerating the hardening efficiency; the setting of the opening and closing component makes it convenient to drive the switch when the protrusion drives the lifting plate to move up to the highest point, so that the switch disconnects the circuit of the motor. At this time, the lifting component loses its locking effect on the height of the heavy hammer, which facilitates the fall of the heavy hammer. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Combined with attachment Figure 1 、 Figure 2 and Figure 3 A construction equipment for rapid hardening of sandy soft foundation, comprising a weight 1, a crane 2 and a boom 3 connected to the crane 2, the boom 3 being connected to a lifting assembly capable of lifting the weight 1, the lifting assembly comprising a motor 11 connected to the boom 3 and lockable after being powered on, a reel 12 being connected to the power output end of the motor 11, a pull rope 13 being connected to the reel 12, the other end of the pull rope 13 being connected to a protrusion 7;

[0023] The motor 11 can drive the winding wheel 12 to drive the pull rope 13 to reel in, thereby achieving the lifting of the protrusion 7 and the heavy hammer 1.

[0024] Combined with attachment Figure 3 and Figure 4The other end of the pull rope 13 passes through the connecting shell 5 and the lifting plate 9 in sequence and is connected to the protrusion 7 at the end. The connecting shell 5 and the lifting plate 9 are relatively connected in the middle with a through hole 14 that cooperates with the pull rope 13. The bottom end of the through hole 14 on the lifting plate 9 is inverted into a smooth rounded corner. The top of the connecting shell 5 is rotatably connected to the two sides of the through hole 14 with a first guide wheel 15. The free end of the lifting arm 3 is rotatably connected to a second guide wheel 16. The pull rope 13 passes through the first guide wheel 15 in sequence and then wraps around the second guide wheel 16.

[0025] The through hole 14 in the above structure facilitates the passage of the pull rope 13. The coordinated arrangement of the first guide wheel 15 and the second guide wheel 16 facilitates the guidance of the pull rope 13 and also reduces the friction on the pull rope 13, thereby extending its service life.

[0026] Combined with attachment Figure 3 and Figure 4 The free end of the lifting arm 3 is hinged with a hinge rod 4, and the other end of the hinge rod 4 is connected to a connecting shell 5. A switch 6 for opening and closing the lifting assembly and an acceleration assembly for increasing the descending acceleration of the heavy hammer 1 are connected in the connecting shell 5. The acceleration assembly includes a protrusion 7 connected to the top of the heavy hammer 1. The bottom end of the connecting shell 5 is relatively connected with a groove 8, and the groove 8 cooperates with the protrusion 7. The protrusion 7 is a cylindrical structure. The groove 8 cooperates with the protrusion 7. The bottom end of the groove 8 is connected with a conical guide groove 17. A lifting plate 9 is slidably connected in the groove 8, and a spring 10 is connected between the lifting plate 9 and the groove 8.

[0027] The lifting assembly squeezes the spring 10 during the lifting process of the weight 1, and the spring 10 accumulates force, so that the weight 1 is not only affected by gravity but also by the elastic force of the spring 10 at the beginning of its fall, thereby accelerating the fall of the weight 1 and increasing the impact.

[0028] Combined with attachment Figure 4 The lifting plate 9 is connected to an opening and closing component that can drive the switch 6 to close. The opening and closing component includes a cylinder connected to the top of the lifting plate 9. The other end of the cylinder is connected to a drive ring 18. The top of the groove 8 is connected to a switch groove that can accommodate the switch 6. The drive ring 18 cooperates with the switch 6.

[0029] The cooperation between the driving ring 18 and the switch 6 in the above structure makes it easy to drive the switch 6 to disconnect the circuit of the motor 11 when the heavy hammer 1 rises to the highest point, thereby releasing the lock on the pull rope 13.

[0030] The specific usage is as follows:

[0031] When the weight falls to the ground, the motor 11 is started, and the motor 11 drives the winding wheel 12 to wind the pull rope 13, thereby driving the protrusion 7 at the other end to drive the weight 1 to rise steadily. The through-hole 14 is provided to facilitate the passage of the pull rope 13. The first guide wheel 15 and the second guide wheel 16 are provided to facilitate the direction of the pull rope 13, and also to reduce the friction between the pull rope 13 and the connecting shell 5 and the lifting arm 3. The weight 1 may swing during the rising process, and the smooth rounded corners can reduce the friction between the pull rope 13 and the lifting arm 3, thereby extending its service life. The conical guide groove 17 is provided to facilitate the guidance of the protrusion 7, thereby preventing the protrusion 7 from swinging during the rising process and failing to cooperate with the groove 8.

[0032] As the weight 1 rises, the lifting assembly drives the protrusion 7 to rise into the groove 8. As the protrusion 7 continues to rise, the protrusion 7 drives the lifting plate 9 to slide upward, causing the spring 10 to compress and store force. When the weight 1 falls, it is not only acted upon by gravity, but also by the elastic force of the spring 10 to return to its original position, thereby increasing the acceleration of the weight 1 when it falls, enhancing the impact of the weight 1 on the soft foundation, and accelerating the hardening efficiency.

[0033] When the protrusion 7 drives the lifting plate 9 to move up to the highest point, it drives the switch 6. The lifting plate 9 drives the cylinder to drive the drive ring 18 to extend into the slot of the switch 6 until the drive ring 18 drives the switch 6 to disconnect the circuit of the motor 11. At this time, the motor 11 is no longer energized and cannot lock the height of the heavy hammer 1, and the heavy hammer 1 begins to fall to the ground.
