Description

Technical Field

[0001] This utility model relates to the field of hydraulic aqueduct construction technology, and in particular to a trench-making machine. Background Technology

[0002] An aqueduct is one of the main structures in water diversion projects. It refers to an elevated water channel that transports water across rivers, canals, valleys, depressions, and roads. Aqueducts are generally formed using a trench-building machine, which includes a formwork system for casting the aqueduct, a main beam for mounting the formwork system, and legs supporting the main beam. To ensure that the aqueduct fabrication meets specifications and design requirements, the elevation of the trench-building machine needs to be adjusted.

[0003] Existing methods for adjusting the elevation of aqueduct construction machines, such as the one disclosed in patent application publication number CN117552349A for large-span hydraulic aqueducts, include a main crossbeam. The bottom of the main crossbeam is equipped with main support legs, which are supported on the piers by main support cylinders, enabling the entire machine to be lifted and freed. The extension and retraction stroke of the cylinders determines the accuracy of the elevation adjustment, thus preventing precise adjustment and making it difficult to guarantee accuracy. Furthermore, the legs directly support the pier surface for elevation adjustment, resulting in poor stability due to surface-to-surface contact, and the adjustment process is prone to swaying or tilting, posing safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a trenching machine that can achieve precise height adjustment.

[0005] The technical solution of this utility model is: a trenching machine, including a template system, a main beam, hanging components and support legs. The template system is suspended below the main beam by multiple hanging components. The support legs are slidably mounted on the main beam so that the support legs are anchored and supported on both sides of the template system. The multiple hanging components can independently extend and retract vertically to adjust the elevation position of the template system.

[0006] In the above scheme, the formwork system and the main beam are connected by adjustable hangers, which can adjust the elevation of the formwork system to achieve the pre-camber of the aqueduct as required by the design and ensure the quality of the aqueduct's formation.

[0007] The hanging component includes a first connector, a second connector, and a twin screw. One end of the first connector is connected to the main beam, and the other end of the first connector is provided with a first sleeve. One end of the second connector is detachably connected to the template system, and the other end of the second connector is provided with a second sleeve. Both the first sleeve and the second sleeve are provided with internal threads. Both ends of the twin screw are threadedly connected to the first sleeve and the second sleeve.

[0008] The hanging components use a twin-screw mechanism to fine-tune the elevation of the formwork system, enabling precise elevation adjustments.

[0009] Preferably, the outrigger includes a column, a wheel box located at the upper end of the column, and a jack extending and retracting at the lower end of the column. The wheel box is adapted to the main beam, and the bottom of the jack outputs anchoring force.

[0010] Preferably, two legs are spaced apart in the width direction of the template system, and the two legs are connected by a crossbeam.

[0011] Preferably, a level is provided on the crossbeam.

[0012] Preferably, the jack is a self-locking hydraulic jack.

[0013] Preferably, a groove pier is provided below the main beam, and an anchoring seat is provided at the lower end of the support leg to be anchored to the groove pier.

[0014] Preferably, the anchorage includes a beam and grippers hinged to both ends of the beam, the hinged grippers opening and closing to clamp or release the groove.

[0015] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0016] I. This utility model uses adjustable hanging parts to connect the template system and the main beam, which can adjust the elevation of the template system to achieve the pre-camber of the aqueduct as required by the design and ensure the quality of the aqueduct forming.

[0017] Second, the hanging components use a double screw mechanism to fine-tune the elevation of the formwork system, enabling precise elevation adjustment and achieving high-precision elevation adjustment of the formwork.

[0018] 3. An anchoring base is added to the lower end of the outrigger to stabilize the clamping pier by anchoring, thereby improving the stability during elevation adjustment, avoiding swaying or tilting, and improving safety.

[0019] Fourth, the combination of hanging components and jacks allows for convenient and quick adjustment of the overall template elevation of the trenching machine;

[0020] 5. A level is installed on the crossbeam connecting the outriggers to monitor the horizontal status of the trenching machine and make adjustments accordingly;

[0021] VI. Select self-locking hydraulic jacks to continuously maintain the jack height and load, ensuring that the elevation of the trough remains unchanged after the trenching machine constructs the trough, thus guaranteeing the forming quality. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0028] like Figure 1 As shown, the trenching machine provided in this embodiment includes a template system 1, a hanging component 2, a main beam 3, support legs 4, and a crossbeam 6.

[0029] like Figure 4 As shown, the formwork system 1 is used to pour concrete to form an aqueduct. Figure 1 As shown, the formwork system 1 is suspended below the main beam 3 by multiple hanging brackets 2. A channel pier 5 is located below the main beam 3. A channel-forming machine is anchored to the channel piers 5 to cast concrete between the channel piers 5 to form a channel.

[0030] like Figure 2As shown, the hanging component 2 includes a first connecting member 21, a second connecting member 22, and a twin screw 25. One end of the first connecting member 21 is connected to the main beam 3, and the other end of the first connecting member 21 is provided with a first sleeve 23. One end of the second connecting member 22 is detachably connected to the formwork system 1, and the other end of the second connecting member 22 is provided with a second sleeve 24. Both the first sleeve 23 and the second sleeve 24 are provided with internal threads, and both ends of the twin screw 25 are threadedly connected to the first sleeve 23 and the second sleeve 24. The twin screw 25 has both positive and negative threads; by turning the middle part, the distance between the twin screw 25 and the first sleeve 23 and the second sleeve 24 can be adjusted simultaneously to achieve the adjustment of the elevation of the formwork system 1 and ensure that the linearity of the formwork system 1 conforms to the shape of the aqueduct body.

[0031] like Figure 1 , Figure 3 As shown, the outrigger 4 includes a column 43, a wheel box 41 located at the upper end of the column 43, a jack 44 extending and retracting at the lower end of the column 43, and an anchoring seat 45 connected to the bottom of the jack 44.

The jack 44 is a self-locking hydraulic jack with a self-locking valve, which can prevent liquid backflow and continuously maintain the extended position and load of the jack 44, ensuring the locking and safety of the height position during trenching machine construction. The jacks 44 on each outrigger 4 can be linked and controlled through a hydraulic control system, enabling rapid adjustment of the trenching machine's elevation.

[0032] like Figure 4 As shown, two support legs 4 are spaced apart along the width of the template system 1, and the two support legs 4 are connected by a crossbeam 6. A level is installed on the crossbeam 6. The wheel box 41 is adapted to the main beam 3 so that the support legs 4 can slide along the main beam 3.

[0033] The anchorage 45 includes a beam 451 and grippers 452 hinged to both ends of the beam 451. The hinged grippers 452 open and close to clamp or release the groove block 5. Figure 1 As shown, two sets of the support legs 4 are provided along the length of the main beam 3, and the two sets of support legs 4 are anchored and supported on both sides of the template system 1.
